Exclusive Radiative B meson decays at Belle

arXiv:0910.0124

Abstract

In this proceeding, we discuss recent results on exclusive radiative B meson decays from the Belle Collaboration. These decays are sensitive to right-handed currents from New Physics. In particular, we measure time-dependent CP violation parameters in B^0->K_Sπ^0γand B^0->K_Sρ^0γdecays, using high-statistics data samples collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^+e^- collider. With the present statistics, these measurements are consistent with the standard model predictions. We also search for the radiative decay B^0->\phiK^0γand report the first observation with a significance of 5.4 σ, including systematic uncertainties.
