| solar neutrino problem: Cosmic Rays at Earth P.K.F. Grieder, 2001-07-27 In 1912 Victor Franz Hess made the revolutionary discovery that ionizing radiation is incident upon the Earth from outer space. He showed with ground-based and balloon-borne detectors that the intensity of the radiation did not change significantly between day and night. Consequently, the sun could not be regarded as the sources of this radiation and the question of its origin remained unanswered. Today, almost one hundred years later the question of the origin of the cosmic radiation still remains a mystery. Hess' discovery has given an enormous impetus to large areas of science, in particular to physics, and has played a major role in the formation of our current understanding of universal evolution. For example, the development of new fields of research such as elementary particle physics, modern astrophysics and cosmology are direct consequences of this discovery. Over the years the field of cosmic ray research has evolved in various directions: Firstly, the field of particle physics that was initiated by the discovery of many so-called elementary particles in the cosmic radiation. There is a strong trend from the accelerator physics community to reenter the field of cosmic ray physics, now under the name of astroparticle physics. Secondly, an important branch of cosmic ray physics that has rapidly evolved in conjunction with space exploration concerns the low energy portion of the cosmic ray spectrum. Thirdly, the branch of research that is concerned with the origin, acceleration and propagation of the cosmic radiation represents a great challenge for astrophysics, astronomy and cosmology. Presently very popular fields of research have rapidly evolved, such as high-energy gamma ray and neutrino astronomy. In addition, high-energy neutrino astronomy may soon initiate as a likely spin-off neutrino tomography of the Earth and thus open a unique new branch of geophysical research of the interior of the Earth. Finally, of considerable interest are the biological and medical aspects of the cosmic radiation because of it ionizing character and the inevitable irradiation to which we are exposed. This book is a reference manual for researchers and students of cosmic ray physics and associated fields and phenomena. It is not intended to be a tutorial. However, the book contains an adequate amount of background materials that its content should be useful to a broad community of scientists and professionals. The present book contains chiefly a data collection in compact form that covers the cosmic radiation in the vicinity of the Earth, in the Earth's atmosphere, at sea level and underground. Included are predominantly experimental but also theoretical data. In addition the book contains related data, definitions and important relations. The aim of this book is to offer the reader in a single volume a readily available comprehensive set of data that will save him the need of frequent time consuming literature searches. |

| solar neutrino problem: The Status of the Solar Neutrino Problem , 1993 Perhaps the most outstanding discrepancy between prediction and measurements in current particle physics comes from the solar neutrino problem, in which a large deficit of high-energy solar neutrinos is observed. Many Nonstandard Solar Models have been invoked to try to reduce the predicted flux, but all have run into problems in trying to reproduce other measured parameters (e.g., the luminosity) of the Sun. Other explanations involving new physics such as neutrino decay and neutrino oscillations, etc. have also been proffered. Again, most of these explanations have been ruled out by either laboratory or astrophysical measurements. It appears that perhaps the most likely particle physics solution is that of matter enhanced neutrino oscillation, the Mikheyev-Smirnov-Wolfenstein (MSW) oscillations. Two new radiochemical gallium experiments, which have a low enough threshold to be sensitive to the dominant flux of low-energy p-p neutrinos, now also report a deficit and also favor a particle physics solution. The next generation of solar experiments promise to finally resolve the source of the ''solar neutrino problem'' by the end of this decade. |
| solar neutrino problem: Towards the Resolution of the Solar Neutrino Problem , 2001 A number of experiments have accumulated over the years a large amount of solar neutrino data. The data indicate that the observed solar neutrino flux is significantly smaller than expected and, furthermore, that the electron neutrino survival probability is energy dependent. This ''solar neutrino problem'' is best solved by assuming that the electron neutrino oscillates into another neutrino species. Even though one can classify the solar neutrino deficit as strong evidence for neutrino oscillations, it is not yet considered a definitive proof. Traditional objections are that the evidence for solar neutrino oscillations relies on a combination of hard, different experiments, and that the Standard Solar Model (SSM) might not be accurate enough to precisely predict the fluxes of different solar neutrino components. Even though it seems unlikely that modifications to the SSM alone can explain the current solar neutrino data, one still cannot completely discount the possibility that a combination of unknown systematic errors in some of the experiments and certain modifications to the SSM could conspire to yield the observed data. To conclusively demonstrate that there is indeed new physics in solar neutrinos, new experiments are aiming at detecting ''smoking gun'' signatures of neutrino oscillations, such as an anomalous seasonal variation in the observed neutrino flux or a day-night variation due to the regeneration of electron neutrinos in the Earth. In this dissertation we study the sensitivity reach of two upcoming neutrino experiments, Borexino and KamLAND, to both of these effects. Results of neutrino oscillation experiments for the case of two-flavor oscillations have always been presented on the (sin[sup 2] 2[theta], [Delta]m[sup 2]) parameter space. We point out, however, that this parameterization misses the half of the parameter space[pi]/4[theta][le][pi]/2, which is physically inequivalent to the region 0[le][theta][le][pi]/4 in the presence of matter effects. The MSW solutions to the solar neutrino problem can extend to the ([theta][pi]/4) side. Furthermore, even the ''vacuum oscillation'' solutions are affected by solar matter effects and hence are different in the two sides. |
| solar neutrino problem: Solar Neutrinos Raymond Davis, Jr., 2018-05-11 A variety of evolutionary sequences of models for the solar interior has been computed, corresponding to variations in input data, to obtain some idea of the uncertainties involved in predicting a solar neutrino flux. It is concluded that the neutrino flux can be estimated to within a factor of 2, the primary uncertainty being the initial homogeneous solar composition; detailed results are given. With a preferred value of the heavy-element-to-hydrogen ratio Z/X = 0.028, the helium content necessary to fit a model to the observed solar luminosity is found to be Y = 0.27. |
| solar neutrino problem: Neutrino Astrophysics John N. Bahcall, 1989-07-28 This authoritative text provides a lively, thought-provoking and informative summary of neutrino astrophysics. Neutrino astronomy is being revolutionized by the availability of new observational facilities. Theoretical work in astrophysics and in particle physics in increasing rapidly. The subject of solar neutrinos has many seemingly independent aspects, both in its theoretical basis (involving nuclear, atomic, and particle physics, geochemistry, and astronomy). For many physicists, solar neutrinos constitute the low-energy frontier of high-energy physics. Results from all these disciplines are combined here, providing a timely and unified discussion of the field. Each chapter begins with a succinct overview of material to be presented and ends with an annotated bibliography. For advanced undergraduate students, but will be essential reading for all researchers interested in the physics of neutrinos and what they reveal about the nature of the Universe. |

| solar neutrino problem: Essays in Nuclear Astrophysics Charles A. Barnes, Donald D. Clayton, D. N. Schramm, 1982-09-30 Originally published in 1982, this collection of essays provides an integrated overview of the application of nuclear science to astronomy. The book discusses, among other topics, the abundances of the nuclear and chemical species on the Earth and the Moon, in meteorites, in the stars, and in interstellar space. The hypothesis that these species are produced by nuclear reactions is then explored and related to laboratory measurements. Other subjects include the dynamics of supernovae and interdisciplinary relationships between elementary particle physics and cosmology. The essays are dedicated to Professor William A. Fowler and pay tribute to his vast influence on the field. |
| solar neutrino problem: Physics and Astrophysics of Neutrinos Masataka Fukugita, Atsuto Suzuki, 2013-12-14 Observations of neutrinos being emitted by the supernova SN1987A, star neutrinos, and atmospheric neutrinos by means of underground detectors have provided new insights into astronomy. These observations have brought to light new unresolved phenomena such as the solar neutrino problem, spurring investigative studies among particle physicists and astrophysicists. Today, intense interaction and continual cooperation between specialists in the field of particle physics and astronomy/cosmology are a pre-requisite for conducting further studies. This book provides detailed elaborations on selected topics. One of the most important features of this book is its enumeration of a number of basic properties of neutrinos and their relationship to Grand Unified Theories. It does not cover all aspects of neutrino theory, but rather focuses on the origin of the neutrino's mass and the generation mixing of neutrinos. The neutrino experiments described were carried out mainly by Japanese researchers. All the kamiokande results, detector performances, and complete references are included. Experiments regarding the neutrino's mass are represented in the direct mass measurement, the double beta-decay experiment, and the neutrino oscillation experiment. The detection of low-energy astrophysical neutrinos is discussed. Particle acceleration mechanisms in astrophysics and the detection of high-energy gamma-rays and neutrinos are also represented. |

| solar neutrino problem: The Physics of Neutrinos Vernon Barger, Danny Marfatia, Kerry Whisnant, 2012-09-30 The physics of neutrinos--uncharged elementary particles that are key to helping us better understand the nature of our universe--is one of the most exciting frontiers of modern science. This book provides a comprehensive overview of neutrino physics today and explores promising new avenues of inquiry that could lead to future breakthroughs. The Physics of Neutrinos begins with a concise history of the field and a tutorial on the fundamental properties of neutrinos, and goes on to discuss how the three neutrino types interchange identities as they propagate from their sources to detectors. The book shows how studies of neutrinos produced by such phenomena as cosmic rays in the atmosphere and nuclear reactions in the solar interior provide striking evidence that neutrinos have mass, and it traces our astounding progress in deciphering the baffling experimental findings involving neutrinos. The discovery of neutrino mass offers the first indication of a new kind of physics that goes beyond the Standard Model of elementary particles, and this book considers the unanticipated patterns in the masses and mixings of neutrinos in the framework of proposed new theoretical models. The Physics of Neutrinos maps out the ambitious future facilities and experiments that will advance our knowledge of neutrinos, and explains why the way forward in solving the outstanding questions in neutrino science will require the collective efforts of particle physics, nuclear physics, astrophysics, and cosmology. |

| solar neutrino problem: Particle Physics Confronts the Solar Neutrino Problem , 1991 This review has four parts. In Part I, we describe the reactions that produce neutrinos in the sun and the expected flux of those neutrinos on the earth. We then discuss the detection of these neutrinos, and how the results obtained differ from the theoretical expectations, leading to what is known as the solar neutrino problem. In Part II, we show how neutrino oscillations can provide a solution to the solar neutrino problem. This includes vacuum oscillations, as well as matter enhanced oscillations. In Part III, we discuss the possibility of time variation of the neutrino flux and how a magnetic moment of the neutrino can solve the problem. WE also discuss particle physics models which can give rise to the required values of magnetic moments. In Part IV, we present some concluding remarks and outlook for the recent future. |

| solar neutrino problem: Astroparticle Physics Claus Grupen, 2020-01-27 This second, revised and thoroughly updated edition of the successful textbook by Claus Grupen describes the branch of astrophysics known as astroparticle physics. Using experimental methods known from cosmic ray and particle physics, astroparticle physics investigates processes of highest energies taking place in the universe. The new edition reports on progress made by recent discoveries in gravitational wave astronomy and neutrino astronomy (including all details needed to understand recent discoveries in multi-messenger experiments) and also astrobiology. After a historical introduction to the basics of elementary particles the author describes their interactions and the relevant detection techniques. The main body of the book concerns cosmic rays as well as particle processes in astrophysics and cosmology including the physics of the early universe. The book provides an orientation in the field of astroparticle physics that many beginners might be looking for.It also presents new sections exploring the interface between particle physics and cosmic radiation and illustrates the impact of particle physics discoveries to astroparticle physics. The physics is presented using little mathematics, and the results are illustrated by many diagrams and illustrative scientific cartoons which ease the reading of the book. Closing the gap between expert and popular level, the book is highly recommended for undergraduate students in physics or astronomy. It also includes an extensive glossary and a detailed index. |
| solar neutrino problem: Introduction to the Physics of Massive and Mixed Neutrinos Samoil Bilenky, 2010-09-14 For many years neutrino was considered a massless particle. The theory of a two-componentneutrino,whichplayedacrucialroleinthecreationofthetheoryof theweakinteraction,isbasedontheassumptionthattheneutrinomassisequalto zero. We now know that neutrinos have nonzero, small masses. In numerous exp- iments with solar, atmospheric, reactor and accelerator neutrinos a new p- nomenon, neutrino oscillations, was observed. Neutrino oscillations (periodic transitionsbetweendifferent?avorneutrinos? ,? ,? )arepossibleonlyifneutrino e ? ? mass-squareddifferencesaredifferentfromzeroandsmalland?avorneutrinosare “mixed”. The discovery of neutrino oscillations opened a new era in neutrino physics: an era of investigation of neutrino masses, mixing, magnetic moments and other neutrino properties. After the establishment of the Standard Model of the el- troweak interaction at the end of the seventies, the discovery of neutrino masses was the most important discovery in particle physics. Small neutrino masses cannot be explained by the standard Higgs mechanism of mass generation. For their explanation a new mechanism is needed. Thus, small neutrino masses is the ?rst signature in particle physics of a new beyond the Standard Model physics. It took many years of heroic efforts by many physicists to discover n- trino oscillations.

| solar neutrino problem: Solar Neutrinos - Proceedings Of The 5th International Solar Neutrino Conference Mikko Meyer, Kai Zuber, 2019-04-26 In 2018 solar physics and neutrino research celebrated various historical highlight events. Among them were 80 years of the paper by Hans Bethe discussing solar fusion cycles as energy source of stars, the first results from the Homestake chlorine experiment celebrating 50 years as well as the discovery of neutrino oscillations 20 years ago by Super-Kamiokande. Since the last International Solar Neutrino Conference in 1997, solar neutrino detection was recognized by two Nobel Prizes, given to Raymond Davis Jr. (2002) and Arthur McDonald (2015).The present proceedings volume is based on the given talks and provides a comprehensive and detailed overview of recent developments and discoveries in the field of solar neutrino physics. Articles were written by renowned experts of their field and cover a wide range in experiments and theory from current and future solar neutrino measurements, elemental abundances, nuclear astrophysics, helioseismology, impact on general neutrino physics and more.

| solar neutrino problem: The H-Function A.M. Mathai, Ram Kishore Saxena, Hans J. Haubold, 2009-10-10 TheH-function or popularly known in the literature as Fox’sH-function has recently found applications in a large variety of problems connected with reaction, diffusion, reaction–diffusion, engineering and communication, fractional differ- tial and integral equations, many areas of theoretical physics, statistical distribution theory, etc. One of the standard books and most cited book on the topic is the 1978 book of Mathai and Saxena. Since then, the subject has grown a lot, mainly in the elds of applications. Due to popular demand, the authors were requested to - grade and bring out a revised edition of the 1978 book. It was decided to bring out a new book, mostly dealing with recent applications in statistical distributions, pa- way models, nonextensive statistical mechanics, astrophysics problems, fractional calculus, etc. and to make use of the expertise of Hans J. Haubold in astrophysics area also. It was decided to con ne the discussion toH-function of one scalar variable only. Matrix variable cases and many variable cases are not discussed in detail, but an insight into these areas is given. When going from one variable to many variables, there is nothing called a unique bivariate or multivariate analogue of a givenfunction. Whatever be the criteria used, there may be manydifferentfunctions quali ed to be bivariate or multivariate analogues of a given univariate function. Some of the bivariate and multivariateH-functions, currently in the literature, are also questioned by many authors. |
| solar neutrino problem: The Quantum Handshake John G. Cramer, 2015-12-23 This book shines bright light into the dim recesses of quantum theory, where the mysteries of entanglement, nonlocality, and wave collapse have motivated some to conjure up multiple universes, and others to adopt a shut up and calculate mentality. After an extensive and accessible introduction to quantum mechanics and its history, the author turns attention to his transactional model. Using a quantum handshake between normal and time-reversed waves, this model provides a clear visual picture explaining the baffling experimental results that flow daily from the quantum physics laboratories of the world. To demonstrate its powerful simplicity, the transactional model is applied to a collection of counter-intuitive experiments and conceptual problems. |

| solar neutrino problem: Neutrino F. E. Close, 2012-02-23 Neutrinos are perhaps the most enigmatic particles in the universe. These tiny, ghostly particles are formed by the billions in stars and pass through us constantly, unseen, at almost the speed of light. Yet half a century after their discovery, we still know less about them than all the other varieties of matter that have ever been seen. In this engaging, concise volume, renowned scientist and writer Frank Close gives a vivid account of the discovery of neutrinos and our growing understanding of their significance, touching on speculative ideas concerning the possible uses of neutrinos and their role in the early universe along the way. Close begins with the discovery of radioactivity by Henri Becquerel and Marie and Pierre Curie, the early model of the atom by Ernest Rutherford, and Wolfgang Pauli's solution to that problem by inventing the concept of neutrino (named by Enrico Fermi, neutrino being Italian for little neutron). The book describes how the confirmation of Pauli's theory didn't occur until 1956, when Clyde Cowan and Fred Reines detected neutrinos, and reveals that the first natural neutrinos were finally detected by Reines in 1965 (before that, they had only been detected in reactors or accelerators). Close takes us to research experiments miles underground that are able to track neutrinos' fleeting impact as they pass through vast pools of cadmium chloride and he explains why they are becoming of such interest to cosmologists--if we can track where a neutrino originated we will be looking into the far distant reaches of the universe. |

| solar neutrino problem: Galileo Unbound David D. Nolte, 2018-07-12 Galileo Unbound traces the journey that brought us from Galileo's law of free fall to today's geneticists measuring evolutionary drift, entangled quantum particles moving among many worlds, and our lives as trajectories traversing a health space with thousands of dimensions. Remarkably, common themes persist that predict the evolution of species as readily as the orbits of planets or the collapse of stars into black holes. This book tells the history of spaces of expanding dimension and increasing abstraction and how they continue today to give new insight into the physics of complex systems. Galileo published the first modern law of motion, the Law of Fall, that was ideal and simple, laying the foundation upon which Newton built the first theory of dynamics. Early in the twentieth century, geometry became the cause of motion rather than the result when Einstein envisioned the fabric of space-time warped by mass and energy, forcing light rays to bend past the Sun. Possibly more radical was Feynman's dilemma of quantum particles taking all paths at once -- setting the stage for the modern fields of quantum field theory and quantum computing. Yet as concepts of motion have evolved, one thing has remained constant, the need to track ever more complex changes and to capture their essence, to find patterns in the chaos as we try to predict and control our world. |
