Parallel talk Flavour Physics and CP Violation Flavour Physics and CP Violation


Luis Miguel Garcia Martin (Univ. of Valencia and CSIC (ES))


In this talk recent results from LHCb on radiative and very rare decays at LHCb are presented.
Radiative b-hadron decays are sensitive probes of New Physics through the study of branching fractions, CP asymmetries and measurements of the polarisation of the photon emitted in the decay. During Run-1 of the LHC, the LHCb experiment has collected large samples of radiative b-hadron decays. The latest measurements will help constrain the size of right-handed currents in extensions of the Standard Model.
Flavour-changing neutral-current processes are loop-suppressed in the Standard Model. Since new particles in SM extensions can give significant contributions, they allow for sensitive searches for phenomena beyond the SM. Very rare decays of b-hadrons that are highly suppressed in the SM are particularly clean probes.
