The ?avor sector carries the largest number of parameters in the Standard Model of particle physics. With no evident symmetry principle behind its existence, it is not as well understood as the SU(3)×SU(2)×U(1) gauge interactions. Yet it tends to be underrated, sometimes even ignored, by the erudite. This is especially so on the verge of the LHC era, where the exploration of the physics of electroweak symmetry breaking at the high energy frontier would soon be the main thrust of the ?eld. Yet, the question of “Who ordered the muon?” by I. I. Rabi lingers. We do not understand why there is “family” (or generation) replication. That three generations are needed to have CP violation is a partial answer. We do not understand why there are only three generations, but Nature insists on (just about) only three active neutrinos. But then the CP violation with three generations fall far short of what is needed to generate the baryon asymmetry of the Universe. We do not understand why most fermions are so light on the weak symmetry breaking scale (v. e. v. ), yet the third-generation top quark is a v. e. v. scale particle. We do not understand why quarks and leptons look so different, in particular, why neutrinos are rather close to being massless, but then have (at least two) near maximal mixing angles. We shall not, however, concern ourselves with the neutrino sector. It has a life of its own.

This volume contains many excellent articles presenting the most recent progress in high energy physics and the current interesting problems concerning flavor physics. The reader will see how flavor physics has become a central area of particle physics, with the Standard Model (SM) being subjected to increasingly precise experiments, and why the remaining puzzles in the SM, such as the mechanisms of symmetry breaking and CP violation, as well as fermion mass and mixing generation, all are mysteries hidden in the physics of flavor. The book also shows that flavor physics is likely to be a window for probing new physics beyond the SM for many years to come.

This book provides a thorough introduction to the phenomenology of heavy flavour physics, those working on the B-factories, LHCb, BTeV, HERA and the Tevatron. It explains how heavy quark theory could be implemented on the lattice, and discusses the status of CP-violation in the neutral kaon system.

This volume contains the edited versions of some selected lectures delivered at the famous "Schladming Winter School", devoted to "Flavor Physics" in the present case. Flavor physics is one of the hot topics in contemporary elementary particle physics, because it relates to fundamental questions like the origin of masses, the size and strength of CP violation and the oscillations between various neutrino species. This volume will be useful for graduate students wishing to get more acquainted with the field as well as for lecturers in search of material for seminars of special lectures and courses in quantum field theory.

The book reviews the latest experimental results of charm and bottom flavor physics at the Tevatron proton-antiproton collider. The measurements of lifetimes, branching ratios and mixing properties of heavy flavored hadrons provide important constraints on fundamental parameters of the standard model – the elements of the CKM matrix. Comparisons of experimental results with theoretical predictions allow to search for physics beyond the standard model or to set bounds on parameters of new physics models. The experimental techniques developed at the Tevatron are highly relevant for the next generation flavor physics experiments at the LHC. This book provides the reader a detailed summary of the status of heavy flavor physics at the end of the Tevatron data taking period and the start of the LHC program.

This book is devoted to the broad subject of flavor physics, embracing the question of what distinguishes one type of elementary particles from another. The articles range from the forefront of formal theory (treating the physics of extra dimensions) to details of particle detectors. Although special emphasis is placed on the physics of kaons, charmed and beauty particles, top quarks, and neutrinos, the articles also dealing with electroweak physics, quantum chromodynamics, supersymmetry, and dynamical electroweak symmetry breaking. Violations of fundamental symmetries such as time reversal invariance are discussed in the context of neutral kaons, beauty particles, electric dipole moments, and parity violation in atoms. The physics of the CabibboOCoKobayashiOCoMaskawa matrix and of quark masses are described in some detail, both from the standpoint of present and future experimental knowledge and from a more fundamental viewpoint, where physicists are still searching for the correct theory.
