Summary of inclusive and exclusive b --> s gamma, b --> d gamma, and b --> s l+ l- measurements

Abstract

Latest experimental progress is reviewed on the searches for physics beyond the Standard Model using the radiative and electroweak penguin decays of B mesons. This review covers inclusive and exclusive measurements of the b --> s gamma, b --> d gamma and b --> s l+ l- processes, including the first observation of B --> K l+ l- and the first attempt to measure the inclusive B --> X(s) l+ l- branching fraction.
