• A bstract 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 → s γ (*) 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 7 γ and $ C_{{^{{7\gamma }}}^{\prime } $ .
