Measurement of time-dependent Charge-Parity asymmetries in neutral charm meson decays — •Daniel Unverzagt1, Dominik Mitzel2, Angelo Di Canto3, and Sascha Stahl2 — 1PI Heidelberg — 2CERN — 3Brookhaven National Laboratory
The measurement of the decay-time-dependent charge-parity (CP) asymmetry in D0 → π+π− and D0 → K+K− is presented using proton-proton collisions. The data was recorded between 2016 and 2018 at a center-of-mass energy of 13TeV with the LHCb detector at the LHC. Neutral D-mesons which arise from semi-leptonic decays of b-flavoured hadrons are used. The charge of the accompanying muon identifies the flavour of the D-meson at the time of production. The analysis strategy is discussed and final results are shown.
