Description
We investigate a new method to probe the helicity of the photon emitted in the b->sγ transition. The method relies on the observation of interference effects between two resonance contributions, B->K*(Kγ)γ and B->ηc(γγ)K or B->χc0(γγ)K to the same final state Kγγ. Decays of the type B->Kres(Kγ)γ dominate the B->Kγγ yield throughout most of the phase space, and may be accessible at current B meson facilities already
