Abstract

First evidence for CPC P violation in two-body singly Cabibbo-suppressed decays of D0D^0 mesons reported by LHCb has recently aroused great interest in charm physics. In this document the latest measurements of CPC P violation in the charm sector are discussed. LHCb and CDF results on time-integrated CPC P asymmetries in D0ππ+D^0 \to \pi^-\pi^+ and D0KK+D^0 \to K^-K^+ decays are presented in some detail. A search for CPC P violation performed by Belle in other two-body decays, namely D0KS0π0D^0 \to K^0_S \pi^0, D0KS0η()D^0 \to K^0_S \eta^{(\prime)}, D(s)+ϕπ+D^+_{(s)} \to \phi \pi^+ and D+π+η()D^+ \to \pi^+ \eta^{(\prime)}, is also presented. Finally, results obtained by CDF with D0KS0π+πD^0 \to K^0_S \pi^+\pi^- decays, as well as by LHCb and BaBar with other multi-body DD decays, are shown.
