Book Description
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 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
CP violation was first observed in 1964, but only in 1999 did we gain much greater experimental insight. Direct CP violation finally appeared in the form of ε′/ε in the K system. Indirect CP violation in B → J/Ψ Ks decay, the raison d'être for construction of e+e- B factories, was first sniffed out at the proton-antiproton collider. The asymmetric B factories — BABAR at SLAC and BELLE at KEK — were completed, while the symmetric B factory at Cornell was upgraded to CLEO-III. It seems that everyone is positioning himself for the great competition on “B Physics and CP Violation”, racing to unravel the Kobayashi-Maskawa matrix, especially the size and origin of CP phases. The change of millennium provides a dramatic backdrop.To have intensive discussions at the technical level, to create broader interest in the subject, and to maximize interaction between experimenters and theorists, this book starts with the status of B factories: accelerator, detector and physics analysis. Following an overview of B physics and the CKM matrix, it delves into the details of lifetime, spectroscopy and decays, with even more specialized discussions on rare decays, direct and indirect CP violation, factorization and final state interactions, determination of unitarity phases, etc. Topics on ε′/ε, rare K decay, charm and hyperon systems, and various T, CP and CPT tests are also discussed at length. The book closes with the outlook for hadron machines and the prospects for new physics. A special feature is that there are two summary talks, one on experiment and the other on theory. The book is further augmented by two dozen excellent contributed talks.

Book Description
"The ultimate question of elementary particle physics is: What is the fundamental Lagrangian of nature surrounding us? The Lagrangian of the SM is very successful in describing nature at the currently available energy range. The discovery of the Higgs boson completed the particle spectrum of the SM and it is another proof of how well the SM works. Nevertheless the SM cannot be the end of the story and it is for sure not the fundamental Lagrangian of nature. The Lagrangian of the SM looses its validity at the latest at the Planck scale where gravitational effects become noticeable.Most physicists think of the SM as an effective theory that has to be replaced by a more fundamental theory above the TeV scale. What the word effective really means will hopefully be clear at later stages of our book. For the time being we will list some problems and open questions of the SM"--
