TESTING THE STANDARD MODEL WITH RADIATIVE PENGUIN DECAYS AT BABAR

摘要

I discuss two recent results in b→ sγ decays from BABAR. The first is a measurement of the branching fraction and photon energy spectrum in the B meson frame of the decay B X,-y. The second result probes the photon polarization via time-dependent CP violation in neutral B decays to K~(*0)y.
