Abstract
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 } $
