Available in PDF, EPUB and Kindle. Book excerpt: 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.
