Current-current operator contribution to the decay matrix in B-meson mixing at next-to-next-to-leading order of QCD

Abstract We compute next-to-next-to-leading order perturbative corrections to the decay width difference of mass eigenstates and the charge-parity asymmetry a fs in flavour-specific decays of neutral B mesons. In our calculation we take into account the full dependence on the charm and bottom quark...
