Abstract

The radiative B\ensuremath→\ensuremathρ\ensuremathγ, B\ensuremath→\ensuremathω\ensuremathγ decay modes are caused by the flavor-changing-neutral-current process, so they give us good insight towards probing the standard model in order to search for new physics. In this paper, we compute the branching ratio, direct CP asymmetry, and isospin breaking effects using the perturbative QCD approach within the standard model.
