Abstract
Radiative decays of b-hadrons are ideal to search for New Physics effects. These decays are sensitive to the polarization of the emitted photon, which can help to constrain New Physics models
in a complementary way to the branching fraction measurements. In this work, I present several
results by the LHCb collaboration related to the photon polarization in b → sγ transitions, with
special emphasis put on the new time-dependent B 0 s → φ γ analysis. Other analyses discussed are
the observation of a non-zero polarization in B + → K + π − π + γ decays, and the angular analysis
of B 0 → K ∗0 e + e − at the photon pole.
