The development in our understanding of symmetry principles is reviewed. Many symmetries, such as charge conjugation, parity and strangeness, are no longer considered as fundamental but as natural consequences of a gauge field theory of strong and electromagnetic interactions. Other symmetries arise naturally from physical models in some limiting situation, such as for low energy or low mass. Random dynamics and attempts to explain all symmetries ? even Lorentz invariance and gauge invariance ? without appealing to any fundamental invariance of the laws of nature are discussed. A selection of original papers is reprinted.

This book is a tribute to Harald Fritzsch (1943-2022), who has made outstanding contributions to the development of modern particle physics. He was a pioneer of QCD, the gauge theory of strong interactions, and contributed significantly to Grand Unified Theories and to the physics of quark and lepton flavors.The present book collects reminiscences of Harald Fritzsch and scientific articles, written by friends, colleagues, collaborators and former students. The contributed articles span a wide range of topics, reflecting Harald's broad interests in physics, from QCD and its applications at high and low energies, the flavor puzzle, flavor symmetries and textures, to gravity, constants of Nature and fundamental symmetries and their violation. The authors of these articles include, among others, Siegfried Bethke, Johannes Blümlein, Stanley J Brodsky, Gerard 't Hooft, Heinrich Leutwyler, Hans Peter Nilles, Serguey T Petcov, Kok Khoo Phua and Willibald Plessas.

This volume brings together international experts in diverse areas of physics to discuss recent progress in the experimental and theoretical study of neutrino oscillations.Readers are brought up to date with the latest developments in important neutrino experiments, and the associated progress in theory is summarized. The principal projects worldwide, such as Super-Kamiokande, SNO, KamLAND, are considered, and contributions also report on future experiments, including JPARC, OPERA, and MINOS.Several other related topics, such as dark matter, double beta decay, lepton flavor violation, and cosmology, are discussed, reflecting the wide-ranging specializations of many contributors outside of pure neutrino physics.

This volume presents the progress made in the study of the Seesaw mechanism and of its implications over the past 25 years, as well as the recent theoretical developments in the understanding of the measured pattern of neutrino masses and mixings. Observable implications of the Seesaw mechanism like leptogenesis or lepton flavour violation in supersymmetric theories are discussed, and the key aspects of the vast experimental program aimed at determining the neutrino parameters and properties are reviewed. The book provides an up-to-date and in-depth perspective on neutrino masses and on the associated physics in the Seesaw scenario.

It is widely accepted that quarks and leptons should be understood on the basis of the same unification scheme. The investigation of hidden rules behind observed quark and lepton mass spectra will provide a very important clue to a unified model of quarks and leptons. Now the investigation is timely because of the recent abundance of data on the CKM matrix elements and neutrino mixings. This volume offers useful information and hints on a unified understanding of quarks and leptons.

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. This invaluable book outlines the development of double beta research from its beginnings until its most recent achievements, and also presents the outlook for its highly exciting future. Contents: Double Beta Decay OCo Historical Retrospective and Perspectives; Original Articles: From the Early Days until the Gauge Theory Era; The Nuclear Physics Side OCo Nuclear Matrix Elements; The Nuclear Physics Side OCo Nuclear Matrix Elements; Effective Neutrino Masses from Double Beta Decay, Neutrino Mass Models and Cosmological Parameters OCo Present Status and Prospects; Other Beyond Standard Model Physics: From SUSY and Leptoquarks to Compositeness and Quantum Foam; The Experimental Race: From the Late Eighties to the Future; The Future of Double Beta Decay; Appendices: Ten Years of HeidelbergOCoMoscow Experiment; The Potential Future OCo GENIUS. Readership: Particle physicists, nuclear physicists and astrophysicists."

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.
