This project deals with theoretical predictions and phenomenological implications for exclusive non-leptonic, rare semi-leptonic and radiative b-hadron decays. We will use factorisation and effective-field-theory methods to understand hadronic uncertainties in different flavour observables. We will present phenomenological updates for angular observables and partial decay rates, and extend our studies to possible flavour structures of physics beyond the Standard Model.
