Radiative Penguin Decays of B Mesons: Measurements of B -> K* gamma, B -> K2*(1430) gamma, and Search for B0 -> phi gamma
Electromagnetic radiative penguin decays of the B meson were studied with the
BaBar detector at SLAC's PEP-II asymmetric-energy B Factory. Branching
fractions and isospin asymmetry of the decay B -> K* gamma, branching fractions
of B -> K2*(1430) gamma, and a search for B0 -> phi gamma are presented. The
decay rates may be enhanced by contributions from non-standard model processes.Comment: 5 pages, 3 figures, presented at the 2004 Meeting of the Division of
