a centre-of-mass energy of 13 TeV. The flavour-tagged decay-time-dependent analysis of about 5700 B0→D+D- signal candidates yields the CP observables S_D+D- = -0.552 ± 0.100 (stat) ± 0.010 (syst), C_D+D- = 0.128 ± 0.103 (stat) ± 0.010 (syst). In the second measurement, approximately 13000 Bs0→Ds+Ds- signal candidates are selected, and the CP observables are determined to be ϕsDs+Ds- = -0.086 ± 0.106 (stat) ± 0.028 (syst) rad, |λDs+Ds-| = 1.145 ± 0.126 (stat) ± 0.031 (syst). These results …
