Available in PDF, EPUB and Kindle. Book excerpt: Motivated by recent experimental indications of large [nu]{sub [mu]} - [nu][tau] mixing, we explore current bounds on the analogous mixing in the charged lepton sector. We present a general formalism for dimension-6 fermionic effective operators involving [tau]-{mu} mixing with typical Lorentz structures and discuss their relationship to the standard model gauge symmetry. We find the low-energy constraints on the new physics scale associated with each operator, mostly from current experimental bounds on rare decay processes of [tau], hadrons or heavy quarks. For operators involving at least one light quark (u, d, s), these constraints typically give a bound on the new physics scale of a few TeV or higher. Those operators with two heavy quarks turn out to be more weakly constrained at present, giving bounds of a few hundred GeV. A few scalar and pseudo-scalar operators are not subject to any current experimental constraints.

Book excerpt: The usage of polarimetry and spin-correlation tests to determine the complete Lorenz structure of the tau lepton's charged and neutral- current couplings is reviewed. The emphasis is on tests for ''something'' in a (V-A)+ ''something'' structure in J[sup charged] Lepton current, so as to bound the scales [lambda] for ''new physics'' such as arising from tau weak magnetism, weak electricity, and/or second-class currents. Tests for T and for CP violation are discussed.
Book Synopsis High Energy Physics by : Amir H. Fariborz
Download or read book High Energy Physics written by Amir H. Fariborz and published by American Institute of Physics. This book was released on 2003-11-11 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are four fundamental forces in nature: gravitational, electromagnetic, weak, and strong forces. The last two are sometimes referred to as nuclear forces. It is the main objective of high energy physics to explore these forces, and hopefully unify them into one fundamental theory. This goal has made high energy physics one of the most ambitious, attractive, challenging, and powerful areas of physics, and has attracted experts from other areas including pure and applied mathematics, and computer science. The MRST annual conference brings together senior and junor investigators and provides a friendly and stimulating atmosphere to discuss recent developments in high energy physics. A broad range of topics in high energy physics was covered in this conference, and therefore these proceedings will be very useful to both senior researchers as well as graduate students in high energy physics, nuclear physics, and computational physics, providing most recent ideas, techniques, and directions for future research in this field.

Download or read book B Decays written by Sheldon Stone and published by World Scientific. This book was released on 1994 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 2nd edition is an extensive update of "B Decays?. The revisions are necessary because of the extensive amount of new data and new theoretical ideas. This book reviews what is known about b-quark decays and also looks at what can be learned in the future.The importance of this research area is increasing, as evidenced by the approval of the luminosity upgrade for CESR and the asymmetric B factories at SLAC and KEK, and the possibility of experiments at hadron colliders.The key experimental observations made thus far, measurement of the lifetimes of the different B species, B0-B0 mixing, the discovery of ?Penguin? mediated decays, and the extraction of the CKM matrix elements Vub and Vcb from semileptonic decays, as well as more mundane results, are described in great detail by the experimentalists who have been closely involved with making the measurements. Theoretical progress in understanding b-quark decays using HQET and lattice gauge techniques are described by theorists who have developed and used these techniques.Synthesizing the experimental and theoretical information, several articles discuss the implications for the ?Standard Model? and how further tests can be done using measurements of CP violation in the B system.

Book Synopsis Flavor Physics and the TeV Scale by : George Wei-Shu Hou
Download or read book Flavor Physics and the TeV Scale written by George Wei-Shu Hou and published by . This book was released on 2019 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of this monograph discusses the usefulness of heavy flavor as a probe of TeV-scale physics, exploring a number of recently-uncovered “flavor anomalies” that are suggestive of possible TeV-scale phenomena. The large human endeavor at the Large Hadron Collider has not turned up any New Physics, except the last particle of the Standard Model, the Higgs boson. Revised and updated throughout, this book puts the first results from the LHC into perspective and provides an outlook for a new era of flavor physics. The author readdresses many questions raised in the first edition and poses new ones. As before, the experimental perspective is taken, with a focus on processes, rather than theories or models, as a basis for exploration, and two-thirds of the book is concerned with b -^ s or bs sb transitions. In the face of the advent of Belle II and other flavor experiments, this book becomes a part of a dialogue between the energy/collider and intensity/flavor frontiers that will continue over the coming decade. Researchers with an interest in modern particle physics will find this book particularly valuable.

This book was released on 2008 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Advances made by physicists in understanding matter, space, and time and by astronomers in understanding the universe as a whole have closely intertwined the question being asked about the universe at its two extremesâ€"the very large and the very small. This report identifies 11 key questions that have a good chance to be answered in the next decade. It urges that a new research strategy be created that brings to bear the techniques of both astronomy and sub-atomic physics in a cross-disciplinary way to address these questions. The report presents seven recommendations to facilitate the necessary research and development coordination. These recommendations identify key priorities for future scientific projects critical for realizing these scientific opportunities.

Book Synopsis The Composite Nambu-Goldstone Higgs by : Giuliano Panico
Download or read book The Composite Nambu-Goldstone Higgs written by Giuliano Panico and published by Springer. This book was released on 2015-11-17 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hierarchy Problem is arguably the most important guiding principle concerning the extension to high-energy scales of the Standard Model (SM) of Fundamental Interactions. Every scenario for addressing this issue unavoidably predicts new physics in the TeV energy range, which is currently being probed directly by the LHC experimental program. Among the possible solutions to the Hierarchy Problem, the scenario of a composite Higgs boson is a very simple idea and a rather plausible picture has emerged over the years by combining the following ingredients: First, the Higgs must be a (pseudo-) Nambu-Goldstone boson, rather than a generic hadron of the new strong sector. Second, through the so-called ‘partial compositeness’, SM particles mix with strong sector resonances with suitable quantum numbers, so that they become a linear combination of elementary and composite degrees of freedom. Recently, general descriptions of the Composite Higgs Scenario were developed which successfully capture the relevant features of this theoretical framework in a largely model-independent way. The present book provides a concise and illustrative introduction to the subject for a broad audience of graduate students and non-specialist researchers in the fields of particle, nuclear and gravitational physics.
Book Synopsis Introduction to High Energy Physics by : Donald H. Perkins
Download or read book Introduction to High Energy Physics written by Donald H. Perkins and published by Cambridge University Press. This book was released on 2000-04-13 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: This highly-regarded text provides a comprehensive introduction to modern particle physics. Extensively rewritten and updated, this 4th edition includes developments in elementary particle physics, as well as its connections with cosmology and astrophysics. As in previous editions, the balance between experiment and theory is continually emphasised. The stress is on the phenomenological approach and basic theoretical concepts rather than rigorous mathematical detail. Short descriptions are given of some of the key experiments in the field, and how they have influenced our thinking. Although most of the material is presented in the context of the Standard Model of quarks and leptons, the shortcomings of this model and new physics beyond its compass (such as supersymmetry, neutrino mass and oscillations, GUTs and superstrings) are also discussed. The text includes many problems and a detailed and annotated further reading list.
Book Synopsis Lepton Flavor Violation at LEP II and Beyond by :
Download or read book Lepton Flavor Violation at LEP II and Beyond written by and published by . This book was released on 1996 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, two fundamental mysteries in particle physics are the origins of electroweak symmetry breaking and the fermion mass matrices. The experimental discovery of superpartners would represent enormous progress in the understanding of electroweak symmetry breaking, but would it also allow progress on the flavor problem? To date, nearly all experimental studies of supersymmetry have ignored the possibility of flavor mixings in the sfermion sector. However, since all superpartners must be given masses, all supersymmetric theories necessarily allow for the possibility of new flavor mixings beyond the standard model. In addition, there are now many supersymmetric theories of flavor, which predict a wide variety of superpartner flavor mixings. In this study, the author examines the possibility of measuring these mixings at LEP II and the Next Linear Collider (NLC). Rare flavor changing processes, such as [mu] → e[gamma], [tau] → [mu][gamma], [tau] → e[gamma], b → s[gamma], and neutral meson mixing, already provide important constraints on the sfermion flavor mixings through the virtual effects of superpartners. However, as will be seen below, once superpartners are discovered, it will be possible to probe these mixings much more powerfully by directly observing the change in flavor occurring at the superpartner production and decay vertices.
