Perspectives In The Standard Model Tasi 91

These proceedings consist of a series of detailed pedagogical lectures on a variety of theoretical and experimental topics. Together they comprise a comprehensive survey of current approaches to the physics of the standard model. The school is slanted to emphasize dynamics, recent theoretical advances, and new experiments.

In this second edition, many chapters (e.g. on electroweak unification) have been revised to bring them up to date. In particular, the chapters neutrino physics, particle mixing and CP violation and weak decays of heavy flavors have beer rewritten incorporating new material and new data. The heavy quark effective theory has been included.

The progress made in particle physics during the last two decades has led to the formulation of the so-called Standard Model of elementary particles and its quantitative experimental test. This book presents that progress, and also includes chapters which provide background on modern particle physics.Particle physics forms an essential part of the physics curriculum. This is a comprehensive book incorporating all the topics for a unified treatment of particle physics. It provides good reference material for researchers in both theoretical and experimental particle physics. It is designed as a semester course for senior undergraduates and for graduate students. Formal quantum field theory is not used. A knowledge of nonrelativistic quantum mechanics is required for some parts of the book, but for the remaining parts familiarity with the Dirac equation and Feynman rules is essential. However, some of these topics are included in an appendix.In this second edition, many chapters (e.g. on electroweak unification) have been revised to bring them up to date.

This PhD thesis is dedicated to a subfield of elementary particle physics called “Flavour Physics”. The Standard Model of Particle Physics (SM) has been confirmed by thousands of experimental measurements with a high precision. But the SM leaves important questions open, like what is the nature of dark matter or what is the origin of the matter-antimatter asymmetry in the Universe. By comparing high precision Standard Model calculations with extremely precise measurements, one can find the first glimpses of the physics beyond the SM – currently we see the first hints of a potential breakdown of the SM in flavour observables. This can then be compared with purely theoretical considerations about new physics models, known as model building. Both precision calculations and model building are extremely specialised fields and this outstanding thesis contributes significantly to both topics within the field of Flavour Physics and sheds new light on the observed anomalies.

This volume gives an up-to-date, useful review of the recent results and new ideas concerning the following topics: precision tests of the standard model, search for Higgs bosons, CP violation, flavour physics, neutrino physics, testing extensions of the standard model, supersymmetry, particle physics, cosmology and new results in strong interactions.

Particle physics and cosmology are united in the standard hot big bang model. This volume contains pedagogical lectures on the experimental and theoretical status of the standard models of particle physics and cosmology as well as their extensions, with an overall focus on the strong interplay between these two fields.

This volume contains the proceedings of one of the first schools devoted to effective field theories. This subject has recently raised great interest in high energy physics and has become extremely useful in the analysis of experimental data. The lectures cover a wide spectrum of applications of effective field theories with a pedagogical approach, also paying attention to the most recent developments.
