Abstract: A bstractBesides being important to determine Standard Model parameters such as the CKM matrix elements |Vcb| and |Vub|, semileptonic B decays seem also promising to reveal new physics (NP) phenomena, in particular in connection with… read more here.

Abstract: We calculate the differential branching fraction, lepton forward-backward asymmetry and direct CP asymmetry for Bd,s → $$ \gamma \mathrm{\ell}\overline{\mathrm{\ell}} $$ decays with an energetic photon. We employ factorization methods, which result in rigorous next-to-leading order… read more here.
