Rare, radiative and EW penguin decays in Heavy flavor hadrons

Rare decays of b-hadrons provide high sensitivity to New Physics effects.Several deviations with respect to the Standard Model predictions have beenobserved in recent years, leading to significant tensions in global fitanalyses. It is thus crucial to update the existing measurements and study newdecay modes to confirm the pattern. The latest results from LHCb on themeasurement of branching fractions and angular distributions in rare b-hadrondecays are presented.
