Book Description
The b [yields] s[gamma] decay represents a possible electromagnetic ''loop'' penguin decay of the B meson. This FCNC process is of high theoretical interest because various scenarios of new physics are expected to have contributions at the same (one loop) level as the Standard Model. The large sample of B[bar B] meson decays collected by the BaBar experiment makes a precision measurement of this rare decay possible. In conjunction with Standard Model predictions at the 10% level, it brings new physics effects into the realm of detection--or seriously constrains models that could predict them. A fully inclusive technique is presented to study the b [yields] s[gamma] transition as a function of photon energy, using 88.5 [+-] 1.0 x 10[sup 6] B[bar B] meson decays collected by the BaBar experiment in the years 2000 to 2002. The expected statistical and systematic uncertainties have been fully determined which enables first comparisons with theoretical predictions and other experimental results. It also lays the basis for the determination of the inclusive branching fraction [Beta](B [yields] X[sub s][gamma]) and the measurement of the photon energy spectrum.

Book Description
The electromagnetic penguin process b [yields] s[gamma] is very interesting to theorists because it can be used to constrain contributions from new physics that could enter at the one loop level. The high statistics of B[bar B] events collected at the BABAR experiment make a measurement of this rare decay possible. The branching fraction of a sum of exclusive b [yields] s[gamma] decay modes is measured as a function of the strange hadronic mass. This is a large step toward the measurement of the b [yields] s[gamma] rate.

Book Description
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.
