Abstract
We investigate a new method to probe the helicity of the photon emitted in the bâsγ transition. The method relies on the observation of interference effects between two resonance contributions, BâKâ(Kγ)γ and Bâηc(γγ)K or BâÏc0(γγ)K to the same final state Kγγ. Decays of the type BâKres(Kγ)γ dominate the BâKγγ yield throughout most of the phase space, and may be accessible at current B meson facilities already.
