Theory Review of Exclusive Rare Radiative Decays
Experimental measurements of B → V γ decays, with V a light vector meson such as K, ρ, ω, φ, have continued to improve and will become more precise at the end of the B-factories and at LHC-b. Given their rich CKM phenomenology and potential to constrain new physics models, having reliable theory predictions for these decays is increasingly relevant. In this talk I briefly review the status of this area. The starting point is the effective weak Hamiltonian, which for B → V γ decays is [1]:
