Book Description
The Standard Model (SM) of particle physics has withstood thus far every attempt by experimentalists to show that it does not describe data. We discuss the SM in some detail, focusing on the mechanism of fermion mixing, which represents one of its most intriguing aspects. We discuss how this mechanism can be tested in b-quark decays, and how b decays can be used to extract information on physics beyond the SM. We review experimental techniques in b physics, focusing on recent results and highlighting future prospects. Particular attention is devoted to recent results from b decays into a hadron, a lepton and an anti-lepton, that show discrepancies with the SM predictions — the so-called B-physics anomalies — whose statistical significance has been increasing steadily. We discuss these experiments in a detailed manner, and also provide theoretical interpretation of these results in terms of physics beyond the SM.

Book Description
The study of rare hadronic B decays at LHCb and at the planned Super-B factories is a valueable tool in the search for new physics. The variety of hadronic decay channels allows for over-constraining measurements of flavour-changing neutral currents. The author discusses several aspects of new physics in rare hadronic B decays. In the first part of the book, the Minimal Supersymmetric Standard Model (MSSM) with Minimal Flavor Violation is analysed. In this model, large effects can occur in rare B decays due to tan(beta)-enhanced corrections which have to be resummed to all orders. The known resummation formulae are generalised beyond the decoupling limit and novel effects in couplings involving genuine supersymmetric particles are studied. In the second part of the book, the possibility of probing new physics in electroweak penguins via hadronic B decays is discussed. Such kind of new physics is suggested by puzzling data in B K, pi decays. The author shows that a measurement of the purely isospin-violating decays Bs phi, pi(rho) could shed light on this puzzle. A model-independent study and a study of concrete well-motivated new physics scenarios are performed.

Book Description
th This volume contains the written versions of invited lectures presented at the 28 "Internationale Universitatswochen fUr Kernphysik" in Schladming, Austria in March 1989. The generous support of our sponsors, the Austrian Ministry of Science and Research, the Government of Styria, and others, made it again possible to invite expert lecturers. The courses were centered on elementary particle physics to be performed with large accelerators accessible in the immediate future, including some reports on the current situation. Thanks to the efforts of the speakers it was possible to obtain excellent surveys. After the School the lecture notes were revised and partially rewritten in TPC by the authors, whom we thank for their labour. Unfortunately the report on the situation at SLAC by M. Swartz could not be included. Thanks are also due to the publishers for their patience. Graz, Austria H. Latal December 1989 H.

Electroweak Symmetry Breaking And New Physics At The Tev Scale

Pages : 749
Book Description
This is an expanded version of the report by the Electroweak Symmetry Breaking and Beyond the Standard Model Working Group which was contributed to Particle Physics — Perspectives and Opportunities, a report of the Division of Particles and Fields Committee for Long Term Planning. One of the Working Group's primary goals was to study the phenomenology of electroweak symmetry breaking and attempt to quantify the “physics reach” of present and future colliders. Their investigations encompassed the Standard Model — with one doublet of Higgs scalars — and approaches to physics beyond the Standard Model. These include models of low-energy supersymmetry, dynamical electroweak symmetry breaking, and a variety of extensions of the Standard Model with new particles and interactions. The Working Group also considered signals of new physics in precision measurements arising from virtual processes and examined experimental issues associated with the study of electroweak symmetry breaking and the search for new physics at present and future hadron and lepton colliders.This volume represents an important contribution to the efforts being made to advance the frontiers of particle physics.
The Anomalous Magnetic Moment of the Muon
Author: Fred JegerlehnerPublisher: Springer Science & Business Media
ISBN: 3540726330
Category : Science
Languages : en
Pages : 433
Book Description
This book reviews the present state of knowledge of the anomalous magnetic moment a=(g-2)/2 of the muon. The muon anomalous magnetic moment is one of the most precisely measured quantities in elementary particle physics and provides one of the most stringent tests of relativistic quantum field theory as a fundamental theoretical framework. It allows for an extremely precise check of the standard model of elementary particles and of its limitations.
Probing New Physics with Boosted H→b ̄b Decays with the ATLAS Detector at 13 TeV

Author: Andrzej J. BurasPublisher: Cambridge University Press
ISBN: 1108882757
Category : Science
Languages : en
Pages : 739
Book Description
This is the first advanced, systematic and comprehensive look at weak decays in the framework of gauge theories. Included is a large spectrum of topics, both theoretical and experimental. In addition to explicit advanced calculations of Feynman diagrams and the study of renormalization group strong interaction effects in weak decays, the book is devoted to the Standard Model Effective Theory, dominating present phenomenology in this field, and to new physics models with the goal of searching for new particles and interactions through quantum fluctuations. This book will benefit theorists, experimental researchers, and Ph.D. students working on flavour physics and weak decays as well as physicists interested in physics beyond the Standard Model. In its concern for the search for new phenomena at short distance scales through the interplay between theory and experiment, this book constitutes a travel guide to physics far beyond the scales explored by the Large Hadron Collider at CERN.
