Rare W → B c + γ decay up to the NNLO and NLL accuracy in QCD
Abstract We perform a detailed theoretical study of the rare radiative decay of the W boson into a B c meson and an on-shell photon. The decay amplitude is described by two independent form factors, which are calculated up to the next-to-next-to-leading order (NNLO) in QCD within the nonrelativistic...
