Studies of B(s)0 → D(∗) +D− decays with the LHCb experiment — •Philipp Ibis, Antje Mödden, and Margarete Schellenberg — Experimentelle Physik 5, TU Dortmund
The LHCb experiment searches for physics beyond the Standard Model by performing high precision tests of beauty and charm hadrons. Among these are decay-time-dependent measurements of CP violation of neutral meson.
In B0 → D(∗)+D− decays, CP violation occurs in the interference of direct decays and decays after mixing of the B0 mesons. Time-dependent measurements of decays of initial B0 and B0 mesons allow the determination of the CP asymmetry and give access to the CKM angle β.
Analyses of CP violation in B0 → D+D− and B0 → D∗ +D− decays are presented using the full LHCb dataset. Also, a measurement of the branching ratio of the decay Bs0 → D∗ +D− relative to B0 → D∗ +D− is presented.
