Abstract
We discuss the possibilities of assessing a non-zero \( C_{{^{{7\gamma }}}}^{\prime } \) from the direct and the indirect measurements of the photon polarization in the exclusive b → sγ(*) decays. We focus on three methods and explore the following three decay modes: B → K *(→ K S π 0)γ, B → K 1(→ Kππ)γ, and B → K *(→ Kπ)ℓ + ℓ −. By studying different New Physics scenarios we show that the future measurement of conveniently defined observables in these decays could provide us with the full determination of C 7γ and \( C_{{^{{7\gamma }}}}^{\prime } \).
