Book Description
This book describes these issues in terms of links, between cosmology, particle and nuclear physics, as well as between cosmology, atmospheric and terrestrial physics. It studies the constituents of dark matter (classified as hot warm and cold) first in terms of their individual structures, and second, in terms of facilities available to detect these structures. Neutrinos are treated as a separate entity. The last chapter details the real-time stories about the "regions" that were not explored thus far, for lack of advanced technology. Their untold stories (which span up to 2010) are illustrated here datewise in full. The book concludes with the latest news that the Large Hadron Collider team at CERN has finally succeeded in producing 7 trillion electronic Volts of energy by creating head-on-collisions of protons and more protons (in search of God-particle).

Book Description
Rare-event searches have played an integral part in the pursuit of physics beyond the Standard Model, offering us the chance to bridge the disparity between our current understanding and observed phenomena such as Dark Matter (DM) or the nature of neutrino masses. Over the last 30 years, these experiments have grown larger and more sophisticated, allowing us to probe new and exciting theories of the universe. At the same time, we have started to apply the technologies and techniques used in rare-event searches to areas of applied physics, for example; reactor monitoring using Coherent Elastic Neutrino Nucleon Scattering (CEvNS) with Ricochet. In this thesis, I will discuss the hardware and analysis techniques required to design, construct, and extract results from these low background, rare-event searches. In particular, I will discuss the hardware and analysis related to the Cryogenic Dark Matter Search (CDMS), CEvNS detection with Ricochet and the measurement of the effective nuclear quenching factor g, via shape analysis of the highly forbidden In-115 beta spectrum. The latter measurement has far reaching consequences for all neutrino-less double beta decay experiments, independent of isotope.

Book Description
For the last few years astrophysicists and elementary particle physicists have been working jointly on the following fascinating phenomena: 1. The solar neutrino puzzle and the question: What happens to the neutrinos on their way from the sun to the earth? 2. The growing evidence that our universe is filled with about 10 times more matter than is visible and the question: What is dark matter made of? 3. The supernovae explosions and the question: What do neutrinos tell us about such explosions and vice versa? The experimental investigation of these phenomena is difficult and involves unconventional techniques. These are presently under development, and bring together such seemingly disparate disciplines as astrophysics and elementary particle physics on the one hand and superconductivity and solid-state physics on the other. This book contains the proceedings of a workshop held in March 1987 at which the above subjects and their experimental investigation were discussed. The proposed experimental methods are very new. They involve frontier developments in low temperature and solid-state physics. The book should be useful to researchers and students who actively work on these subjects or plan to enter the field. It also offers the non-expert reader with some physics background a good survey of the activities in this field.

The other is the search for the neutrinoless double-beta decay at its ?-value, ?_?? = (2457.83$\pm$0.37)\,keV. The analysis demonstrated that the relative energy resolution at one ?/? is as low as (0.80±$0.02) % in its one-ton fiducial mass, and for single-site interactions at ?_??, a world-leading resolution in ??e experiment that enhance the experimental sensitivity to the neutrinoless double-beta decay events.

Book Description
Updated with a new three-page introduction and three additional articles from 1998 and 2001, this collection of reprints focuses on solar models, neutrino experiments, nuclear reactions, neutrino oscillations and mixing, and helioseismology. The new papers (there are now 113 published between 1964 and 2001) report results of experiments at the Super-Kamiokande and Sudbury Neutrino Observatories and show that helioseismological measurements confirm the standard solar model predictions. There is no index. Annotation copyrighted by Book News, Inc., Portland, OR

Book Description
In this essential, Claus Grupen discusses astroparticle physics in a short historical outline and describes the latest results without going into mathematical detail. As an introduction to this new field of research, he gives an overview of what happens in the sky, between stars and between galaxies. By now, many things are quite well understood, but with every solution found, new questions arise - the author also deals with this spectrum of questions with some answers. Today, astroparticle physics is an active, interdisciplinary field of research that includes and combines astronomy, cosmic rays and elementary particle physics. This Springer essential is a translation of the original German 1st edition essentials, Neutrinos, Dunkle Materie und Co. by Claus Grupen, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2021.The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors

Book Description
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.
