LHCb - Measurement of CP violation in B0→D∗±D∓ decays at LHCb

Abstract

The decay-time-dependent \ensuremath{C\!P} asymmetry in $B^0 \to D^{*\pm}D^{\mp}$ decays is measured using a data set corresponding to an integrated luminosity of $9$\ensuremath{\fb^{-1}} recorded by the \lhcb detector in proton-proton collisions at centre-of-mass energies of 7, 8 and $13$\aunit{Te\kern -0.1em V}. The analysis provides the most precise single measurement of \ensuremath{C\!P} violation in this decay channel to date. All parameters are consistent with their current world average values
