Изучение поляризации фотона в распаде $B_{s} \to \phi\gamma$ детекторе LHCb

The thesis is dedicated to the Monte Carlo analysis of the radiative decay Bs->phi gamma at LHCb. The main attention is drawn to the study of the photon polarization measurement through the CP-violating effects. The statistical error of the CP-violation parameters is estimated with the toy Monte Carlo simulation.
