Nathan Jurek (U. Oxford) "Observation of CP violation in charm decays (and more charming topics)"

June 6, 2019 @ 4:00 pm - 5:00 pm

Precision measurements of the violation of charge-parity (CP) symmetry are crucial for testing the Standard Model and are sensitive probes for new physics contributions. While CP violation has been well-established by several different experiments in the decays of mesons containing strange and bottom quarks, searches for CP violation in the decays of charm mesons had until recently come up empty-handed. Thanks to its unprecedentedly large samples of charm mesons, the LHCb collaboration has succeeded in observing CP violation in the charm sector for the first time via a time-integrated analysis of D0→K−K+ and D0→π−π+ decays. These results will be presented, along with recent time-dependent measurements which help constrain additional sources of CP violation in neutral charm mesons. Finally, projections of future prospects in charm physics will be given.
