Experimentally, the phases $\phi_d$ and $\phi_s$ are determined from CP asymmetry measurements in the ``golden modes" $B_d^0\to J/\psi K^0$ and $B_s^0\to J/\psi\phi$. At leading order, the theoretical interpretation of these measurements is straightforward. However, to reach high precision determinations of $\phi_d$ and $\phi_s$, which is desirable in view of the searches for signs of beyond...
The CP violation observed in the hadronic decays of charmed mesons remains a puzzling open question for theorists. Calculations relying on the assumption of inelastic final-state interactions occurring between pairs of pions and kaons fall short of the experimental value. It has been pointed out that a third channel of four pions can leave imprints on the CP asymmetries of the two-body decays....
LHCb has collected the world’s largest sample of charmed hadrons. This sample is used to precisely measure meson-antimeson mixing and CP violation, and to perform precise measurements of properties and production of charmed mesons. New measurements of several decay modes are presented, including preliminary results obtained with the new LHCb Upgrade I detector.
LHCb is playing a crucial role in the study of rare and forbidden semileptonic decays of charm hadrons, which might reveal interactions beyond the Standard Model. We present the latest measurements of charm decays with two leptons in the final state.
