Book excerpt: The authors discuss [beta] decay interactions in extensions of the Standard Model, and the role of [beta] decay experiments in obtaining information on them. Nuclear and neutron [beta] decay played an important role in the development of the Standard Model (SM). Today a major motivation for their further experimental study is the importance of searching for new-interactions. Despite the remarkable success of the SM, for many theoretical reasons the existence of new physics is expected. In fact, we have already the first strong experimental evidence, in the form of neutrino oscillations, that some extension of the SM is required. In this talk we shall discuss [beta] decay interactions in extensions of the SM [1]. We shall review the existing bounds on new interactions provided by [beta] decay experiments, and consider the constraints on them from other sources. In the next section we focus on time-reversal (T) invariant contributions. In Section 3 we discuss briefly the contributions from the T-violating components of the new interactions. Section 4 contains our conclusions.

Available in PDF, EPUB and Kindle. Book excerpt: Nuclear double beta decay is one of the most promising tools for probing beyond-the-standard-model physics on beyond-accelerator energy scales. It is already now probing the TeV scale, on which new physics should manifest itself according to theoretical expectations. Only in the early 1980s was it known that double beta decay yields information on the Majorana mass of the exchanged neutrino. At present, the sharpest bound for the electron neutrino mass arises from this process. It is only in the last 10 years that the much more far-reaching potential of double beta decay has been discovered. Today, the potential of double beta decay includes a broad range of topics that are equally relevant to particle physics and astrophysics, such as masses of heavy neutrinos, of sneutrinos, as SUSY models, compositeness, leptoquarks, left-right symmetric models, and tests of Lorentz symmetry and equivalence principle in the neutrino sector. Double beta decay has become indispensable nowadays for solving the problem of the neutrino mass spectrum and the structure of the neutrino mass matrix OCo together with present and future solar and atmospheric neutrino oscillation experiments. Some future double beta experiments (like GENIUS) will be capable to be simultaneously neutrino observatories for double beta decay and low-energy solar neutrinos, and observatories for cold dark matter of ultimate sensitivity.

Available in PDF, EPUB and Kindle. Book excerpt: In the last 20 years the disciplines of particle physics, astrophysics, nuclear physics and cosmology have grown together in an unprecedented way. A brilliant example is nuclear double beta decay, an extremely rare radioactive decay mode, which is one of the most exciting and important fields of research in particle physics at present and the flagship of non-accelerator particle physics. While already discussed in the 1930s, only in the 1980s was it understood that neutrinoless double beta decay can yield information on the Majorana mass of the neutrino, which has an impact on the structure of space-time. Today, double beta decay is indispensable for solving the problem of the neutrino mass spectrum and the structure of the neutrino mass matrix. The potential of double beta decay has also been extended such that it is now one of the most promising tools for probing beyond-the-standard-model particle physics, and gives access to energy scales beyond the potential of future accelerators. This book presents the breathtaking manner in which achievements in particle physics have been made from a nuclear physics process. Consisting of a 150-page highly factual overview of the field of double beta decay and a 1200-page collection of the most important original articles, the book outlines the development of double beta decay research theoretical and experimental from its humble beginnings until its most recent achievements, with its revolutionary consequences for the theory of particle physics. It further presents an outlook on the exciting future of the field.

Download or read book Neutrinos and Implications for Physics Beyond the Standard Model written by Robert Schrock and published by World Scientific. This book was released on 2003 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important book presents the proceedings of the conference ?Neutrinos and Implications for Physics Beyond the Standard Model?, put on by the Yang Institute for Theoretical Physics, State University of New York at Stony Brook.The observation of neutrino masses and lepton mixing constitutes the first confirmed evidence for physics beyond the Standard Model. This evidence includes the measured deficiency of charged current reactions induced by solar neutrinos and the anomalous zenith angle distribution of atmospheric neutrinos. A profound question now facing theorists is: What do these observations imply for new physics? At the conference, members of the major experiments gave an update on current experimental evidence from solar and atmospheric neutrino data for neutrino oscillations, and status reports from KamLAND and MiniBooNE. Leading theorists also reported on neutrinoless double beta decay, high energy neutrino scattering and precision electroweak data, theoretical models for neutrino masses and lepton mixing, and constraints from neutrino data, etc. Since neutrino physics is at present one of the most exciting areas of particle physics, this volume should be of interest to a wide variety of students and researchers in physics.

Available in PDF, EPUB and Kindle. Book excerpt: Part of the Physics in a New Era series of assessments of the various branches of the field, Elementary-Particle Physics reviews progress in the field over the past 10 years and recommends actions needed to address the key questions that remain unanswered. It explains in simple terms the present picture of how matter is constructed. As physicists have probed ever deeper into the structure of matter, they have begun to explore one of the most fundamental questions that one can ask about the universe: What gives matter its mass? A new international accelerator to be built at the European laboratory CERN will begin to explore some of the mechanisms proposed to give matter its heft. The committee recommends full U.S. participation in this project as well as various other experiments and studies to be carried out now and in the longer term.

Book excerpt: Kappa Distributions: Theory and Applications in Plasmas presents the theoretical developments of kappa distributions, their applications in plasmas, and how they affect the underpinnings of our understanding of space and plasma physics, astrophysics, and statistical mechanics/thermodynamics. Separated into three major parts, the book covers theoretical methods, analytical methods in plasmas, and applications in space plasmas. The first part of the book focuses on basic aspects of the statistical theory of kappa distributions, beginning with their connection to the solid backgrounds of non-extensive statistical mechanics. The book then moves on to plasma physics, and is devoted to analytical methods related to kappa distributions on various basic plasma topics, spanning linear/nonlinear plasma waves, solitons, shockwaves, and dusty plasmas. The final part of the book deals with applications in space plasmas, focusing on applications of theoretical and analytical developments in space plasmas from the heliosphere and beyond, in other astrophysical plasmas. Kappa Distributions is ideal for space, plasma, and statistical physicists; geophysicists, especially of the upper atmosphere; Earth and planetary scientists; and astrophysicists. Answers important questions, such as how plasma waves are affected by kappa distributions and how solar wind, magnetospheres, and other geophysical, space, and astrophysical plasmas can be modeled using kappa distributions Presents the features of kappa distributions in the context of plasmas, including how kappa indices, temperatures, and densities vary among the species populations in different plasmas Provides readers with the information they need to decide which specific formula of kappa distribution should be used for a certain occasion and system (toolbox)

Download or read book A Neutrino Mass Model Relating the Neutron Decay Anomaly Via Dark Matter written by Ting-hsien Chen and published by . This book was released on 2020 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inside the nucleus, there are protons and neutrons and they form the bound states. When neutron leave the nucleus, it will become an unstable particle which is called a free neutron. The free neutron lifetime is predicted to be 881.5±1.5 s by the Standard Model. For years the experimental measurement are basically consistent with the theoretical results. However, recently laboratories in USA (Beam experiment) and France (Bottle experiment) were shown that the neutron lifetime anomaly, namely a discrepancy of about 1% is found between the experimental measurements and the theoretical prediction. Regarding the neutron lifetime anomaly. We propose an new gauge U(1) symmetry portal to dark matter to resolve the neutron lifetime anomaly. The symmetry breaking pattern of this new gauge symmetry will also shed light on the neutrino mass generation through the quantum radioactive corrections.
