Description

New Physics in the heavy quark sector could arise in decay rates, CP parameters, or the chirality of the final state particles. The LHCb experiment can measure the photon polarization of several rare decays in which a penguin diagram is involved, probing the V-A coupling of the W boson to left-handed quarks in electroweak interactions. This talk will be center in the analysis of angular distributions of radiative b-baryons decays to measure the photon polarization.
