Download or read book Neutrino Mass and Mixing, and Non-accelerator Experiments written by and published by . This book was released on 1992 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: We review the current status of experimental knowledge about neutrinos derived from kinematic mass measurements, neutrino oscillation searches at reactors and accelerators, solar neutrinos, atmospheric neutrinos, and single and double beta decay. The solar neutrino results yield fairly strong and consistent indication that neutrino oscillations are occurring. Other evidence for new physics is less consistent and convincing.

Book Synopsis Neutrino Physics by : Hans V. Klapdor
Download or read book Neutrino Physics written by Hans V. Klapdor and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutrinos play an intriguing role in modern physics linking central questions of particle physics, cosmology and astrophysics. The contributions in this book reflect the present status of neutrino physics with emphasis on non-accelerator or beyond-accelerator experiments. Since a nonvanishing neutrino mass would yield an important boundary condition for GUT, SUSY or Superstring models and since neutrinos are the best candidates for dark matter in the universe, the many efforts to look for a neutrino mass, ranging from neutrino oscillation experiments using reactors, accelerators or the sun as neutrino sources, to tritium decay experiments and the search for neutrinoless double beta decay, are described in some detail. One of the sections is devoted to neutrinos from collapsing stars, including the supernova SN 1987 A. Possibilities for detecting cosmological neutrinos are discussed and an outlook to future experiments is given.

This book was released on 2010-09-14 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. After the ?rst period of investigation of neutrino oscillations, manychallengingproblemsremainedunsolved.Oneofthemostimportantisthe problem of the nature of neutrinos with de?nite masses. Are they Dirac n- trinos possessing a conserved lepton number which distinguish neutrinos and antineutrinos or Majorana neutrinos with identical neutrinos and antineutrinos? Many experiments of the next generation and new neutrino facilities are now under preparation and investigation. There is no doubt that exciting results are ahead.

This book was released on 2016-01-13 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Takaaki Kajita and Arthur McDonald have been jointly awarded the 2015 Nobel Prize in Physics "for the discovery of neutrino oscillations, which shows that neutrinos have mass". Takaaki Kajita is a Japanese physicist who is well known for neutrino experiments at the Kamiokande and the even more outsized Super-Kamiokande. This volume of collected works of Kajita on neutrino oscillations provides a good glimpse into the rise of Asian research in the frontiers of neutrino physics. Japan is now a major force in the study of the three families of neutrinos. Much remains to be done to clarify the Dirac vs. Majorana nature of the neutrino, and the cosmological implications of the neutrino. The collected works of Kajita and his Super-Kamiokande group will leave an indelible footprint in the history of big and better science.

Book Synopsis Particle Physics and Cosmology by : Jose F. Nieves
Download or read book Particle Physics and Cosmology written by Jose F. Nieves and published by American Institute of Physics. This book was released on 2003-02-25 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Standard Model of the electromagnetic and weak interactions offers no explanations for the origin of the fermion mass and mixing parameters, except that they arise from Yukawa couplings, which are free parameters of the Model. The problem is worse when the question of neutrino masses is considered and, despite its remarkable success on many fronts, the Standard Model cannot explain some important experimental observations. In particular, it is not possible to describe the phenomena of neutrino oscillations that has been uncovered in recent years and, from a particle physics viewpoint, this provides the most convincing evidence for physics beyond the Standard Model. Following the trend of the previous workshops, we focus also on the presentation of the current status of the main accelerator and non-accelerator neutrino mass experiments (such as Super-Kamiokande, and SNO), the future experimental projects (e.g., MiniBoone) and some of the phenomenology related to them, as well as reviews of the theoretical and phenomenological ideas related to the question of neutrino masses and related topics such as the explanation for the observed baryon asymmetry in the universe.
Book Synopsis Measurements of Neutrino Mass by : F. Ferroni
Download or read book Measurements of Neutrino Mass written by F. Ferroni and published by IOS Press. This book was released on 2009-09-29 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers a valuable insight into various aspects of the ongoing work directed at measuring neutrino mass. It took twenty years to refute the assertions of Bethe and Peierls that neutrinos were not observable, but it has since been realised that much can be learnt from these particles. The moral is, as Fiorini argues here, that the study of neutrinos was and remains demanding but rewarding. Subjects addressed in this volume include; clarifying the meaning of the Klapdor-Kleingrothaus results, probing the Majorana nature of neutrinos, observing lepton number violating effects for the first time, studying the end point of the spectrum in the search for neutrino masses and speculating whether it is possible to measure neutrino masses in cosmology. Lectures are enriched with rich historical overviews and valuable introductory material. Attention is also given to theoretical topics such as the evolution of the concept of mass in particle physics, a status report on neutrino oscillations and current discussion on neutrino masses. The reader is further reminded that neutrino masses may also have some bearing on the very origin of the matter among us, and have many deep links with other important lines of current physics research.

Book Synopsis Neutrino Factory: Physics and R & D Status by :
Download or read book Neutrino Factory: Physics and R & D Status written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years exciting experimental discoveries have shown that neutrino flavors oscillate, and hence that neutrinos have nonzero masses and mixings. The Standard Model needs to be modified to accommodate neutrino mass terms, which require either the existence of right-handed neutrinos to create Dirac mass terms, and/or a violation of lepton number conservation to create Majorana mass terms. The observation that neutrino masses and mass-splittings are tiny compared to the masses of any of the other fundamental fermions suggests radically new physics, which perhaps originates at the GUT or Planck Scale, or perhaps indicates the existence of new spatial dimensions. Whatever the origin of the observed neutrino masses and mixings is, it will certainly require a profound extension to our picture of the physical world. The first step towards understanding this new physics is to pin down the measurable parameters, and address the first round of basic questions: (1) Are there only three neutrino flavors, or do light sterile neutrinos exist? Are there any other deviations to three-flavor mixing? (2) There is one angle [theta][sub 13] in the mixing matrix which is unmeasured. Is it non-zero? (3) We don't know the mass-ordering of the neutrino mass eigenstates. There are two possibilities, the so-called ''normal'' or ''inverted'' hierarchies. Which is right? (4) There is one complex phase [delta] in the mixing matrix which is accessible to neutrino oscillation measurements. If both [theta][sub 13] and sin [delta] are non-zero there will be CP Violation in the lepton sector. Is sin [delta] non-zero? (5) What precisely is the value of the lightest neutrino mass and are neutrino masses generated by Majorana mass terms, Dirac mass terms, or both? All of these questions, with the exception of the last one, can in principle be addressed by accelerator-based neutrino oscillation experiments. However, getting all of the answers will not be easy, and will require the right experimental tools. A Neutrino Factory appears to be the ultimate tool for probing appears to be the ultimate tool for probing neutrino oscillations. Hence the interest in this new type of neutrino source.

Available in PDF, EPUB and Kindle. Book excerpt: Neutrinos are among nature's fundamental constituents, and they are also the ones about which we know least. Their role in the universe is widespread, ranging from the radioactive decay of a single atom to the explosions of supernovae and the formation of ordinary matter. Neutrinos might exhibit a striking property that has not yet been observed. Like the back-and-forth swing of a pendulum, neutrinos can oscillate to-and-from among their three types (or flavors) if nature provides certain conditions. These conditions include neutrinos having mass and a property called {open_quotes}mixing.{close_quotes} The phenomenon is referred to as neutrino oscillations. The questions of the origin of neutrino mass and mixing among the neutrino flavors are unsolved problems for which the Standard Model of particle physics holds few clues. It is likely that the next critical step in answering these questions will result from the experimental observation of neutrino oscillations. The High Energy Physics Advisory Panel (HEPAP) Subpanel on Accelerator-Based Neutrino Oscillation Experiments was charged to review the status and discovery potential of ongoing and proposed accelerator experiments on neutrino oscillations, to evaluate the opportunities for the U.S. in this area of physics, and to recommend a cost-effective plan for pursuing this physics, as appropriate. The complete charge is provided in Appendix A. The Subpanel studied these issues over several months and reviewed all the relevant and available information on the subject. In particular, the Subpanel reviewed the two proposed neutrino oscillation programs at Fermi National Accelerator Laboratory (Fermilab) and at Brookhaven National Laboratory (BNL). The conclusions of this review are enumerated in detail in Chapter 7 of this report. The recommendations given in Chapter 7 are also reproduced in this summary.

Book Synopsis Massive Neutrinos: Flavor Mixing Of Leptons And Neutrino Oscillations by : Harald Fritzsch
Download or read book Massive Neutrinos: Flavor Mixing Of Leptons And Neutrino Oscillations written by Harald Fritzsch and published by World Scientific. This book was released on 2015-08-28 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of neutrino oscillations neutrino physics has become an interesting field of research in physics. They imply that neutrino must have a small mass and that the neutrinos, coupled to the charged leptons, are mixtures of the mass eigenstates, analogous to the flavor mixing of the quarks. The mixing angles for the quarks are small, but for the leptons two of the mixing angles are large. The masses of the three neutrinos must be very small, less than 1 eV, but from the oscillation experiments we only know the mass differences — the absolute masses are still unknown. Also we do not know, if the masses of the neutrinos are Dirac masses, as the masses of the charged leptons and of the quarks, or whether they are Majorana masses.In this volume, an overview of the present state of research in neutrino physics is given by well-known experimentalists and theorists. The contents — originated from talks and discussions at a recent conference addressing some of the most pressing open questions in neutrino physics — range from the oscillation experiments to CP-violation for leptons, to texture zero mass matrices and to the role of neutrinos in astrophysics and cosmology.

This book was released on 2018-03-23 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: The neutrino is the most fascinating elementary particle due to its elusive nature and outstanding properties that have attracted the interest of generations of physicists since 1930, when it was first postulated by Wolfgang Pauli as a 'desperate remedy' to explain the apparent energy violation in the beta decay. Many fundamental discoveries in particle physics had the neutrino involved in one way or another. To date, neutrino physics is still one of the hottest topics of modern particle physics. Key experiments and significant theoretical developments have contributed in building up what we can call now the Standard Model of Neutrino Physics.The aim of the book is to provide graduate students and young researchers a comprehensive tutorial in modern neutrino physics, specially tailored with emphasis on the educational aspects. It provides an overview of the basics and of recent achievements in the field, from both experimental and theoretical points of view.
