Measurement of $CP$ violation in $B^0\to D^{\ast \pm }{D}^{\mp }$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +901

The decay-time-dependent $CP$ asymmetry in $B^0\to D^{\ast \pm }{D}^{\mp }$ decays is measured using a data set corresponding to an integrated luminosity of $9$fb${}^{-1}$ recorded by the L…
