Cp Asymmetry, Branching Ratios, And Isospin Breaking Effects In B ->Rho Gamma And B ->Omega Gamma Decays With The Perturbative Qcd Approach

The radiative B ->rho gamma, B ->omega gamma 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.
