### Description

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.
