Theory And Phenomenology Of Sparticles

Supersymmetry or SUSY, one of the most beautiful recent ideas of physics, predicts sparticles existing as superpartners of particles. This book gives a theoretical and phenomenological account of sparticles. Starting from a basic level, it provides a comprehensive, pedagogical and user-friendly treatment of the subject of four-dimensional N=1 supersymmetry as well as its observational aspects in high energy physics and cosmology. Part One of the book introduces the requisite formal theory, preceded by a discussion of the naturalness problem. Part Two describes the supersymmetrization of the Standard Model of particle interactions as well as the origin of soft supersymmetry breaking and how it can be mediated from higher energies. Search strategies for sparticles, supersymmetric Higgs bosons, nonminimal scenarios and cosmological implications are some of the other topics covered. Novel features of the book include a dictionary between two-component and four-component spinor notation, a step-by-step derivation of the nonrenormalization theorem, an extended discussion of supersymmetric renormalization group evolution, detailed analyses of minimal and nonminimal models with gravity (including anomaly) mediated and gauge mediated supersymmetry breaking as well as elaborate self-contained presentations of collider signals of sparticles plus supersymmetric Higgs bosons and of supersymmetric cosmology. Appendices list all Feynman rules for the vertices of the Minimal Supersymmetric Standard Model.

Keywords:Reviews: “I find the book very attractive and very useful at this time. There are not so many up-to-date books for the LHC phenomenology.” G Altarelli CERN “It seeks to be the complete primer on supersymmetry for the theorist, phenomenologist and experimentalist. The presentation is lucid throughout and the notation is well-chosen. This is a highly recommended book for the student of particle physics who has studied the basics of quantum field theory and the phenomenon of the known elementary particles. In addition, it is a handy source of information (and most valuably, explanations) for senior students and practicing physicists in other areas, who will increasingly feel the need to know about the area of fundamental science most finely poised for a dramatic experimental breakthrough.” Current Science “… very informative book on supersymmetric particles …” Professor Barry Barish California Institute of Technology “Very good text. Although suitable for those who want to begin working in the field, nonexperts can get substantial insights into the goals and motivation behind the theory by browsing through. The book begins with a good pedagogical treatment of the superspace formalism and ends with an extensive summary of Feynman rules. About 300 pages cover the phenomenology of supersymmetry — from colliders to dark matter — with significant discussion of supersymmetry breaking and a 30-page chapter on supersymmetric Higgs bosons.” Physics Today

PASCOS is an interdisciplinary symposium on the interface of of Particle physics, String theory and Cosmology. Over the past two decades these three disciplines have increasingly become closer. Historically there was always a strong overlap between particle physics and cosmology. This connection has become even stronger with the realization that some of the fundamental issues in cosmology such as the presence of dark matter and dark energy may possibly find a resolution only via new theories of particle physics. At the same time string theory has begun to play an increasingly important role in particle physics as a possible framework for building unified models of particle interaction including gravity. In recent years we have seen an increasing overlap between cosmology and string theory and currently the area of string cosmology is one of the most active fields of research. PASCOS 2005 aimed to provide coherent discussions of recent developments on the interface of the three disciplines and also on their interconnections. In particular, superstring aspects in low energy particle theory (SUSY) and cosmological applications (moduli stabilization) are extensively covered in this volume. Topics include dark matter and dark energy, baryogenesis, flavor and CP violation, neutrino physics, supersymmetry and extra dimensions, flux compactification, string model building, as well as brane cosmology.

A systematic introduction to string phenomenology, outlining how string theory is connected to the real world of particle physics.

This books aims at giving an overview over theoretical and phenomenological aspects of particle astrophysics and particle cosmology. To be of interest for both students and researchers in neighboring fields of physics, it keeps a balance between well established foundations that will not significantly change in the future and a more in-depth treatment of selected subfields in which significant new developments have been taking place recently. These include high energy particle astrophysics, such as cosmic high energy neutrinos, the interplay between detection techniques of dark matter in the laboratory and in high energy cosmic radiation, axion-like particles, and relics of the early Universe such as primordial magnetic fields and gravitational waves. It also contains exercises and thus will be suitable for both introductory and advanced courses in astroparticle physics.

This OA text develops the basic concepts of supersymmetry for experimental and phenomenological particle physicists and graduate students.

A collection of lectures from eight authoritative speakers, High Energy Phenomenology is a concise introduction for postgraduates new to the field and provides a comprehensive overview of important research activities, results, and future directions for existing researchers. Coverage includes Ian Aitchison's introduction of standard model foundations, HERA physics, the physics and experimental challenges of future hadron colliders, and particle physics and cosmology. The book concludes with Alain Blondel's chapter on precision tests of the standard electroweak model at LEP.
