| dc.description.abstract | The CP asymmetries of seven B− decays to two charm mesons are measured using data corresponding to an integrated luminosity of 9 fb−1 of proton-proton collisions collected by the LHCb experiment. Decays involving a D∗0 or D∗− s meson are analysed by reconstructing only the D0 or D− s decay products. This paper presents the frst measurement of ACP (B− → D∗− s D0 ) and ACP (B− → D− s D∗0 ), and the most precise measurement of the other fve CP asymmetries. There is no evidence of CP violation in any of the analysed decays. Additionally, two ratios between branching fractions of selected decays are measured. | - |
