The Standard Model contribution to D0-anti-D0 mixing is dominated by the contributions of light s and d quarks. Neglecting the tiny effects due to b quark, both mass and lifetime differences vanish in the limit of SU(3) symmetry. Thus, the main challenge in the Standard Model calculation of the mass and width difference in the D0-anti-D0 system is to estimate the size of SU(3) breaking effects. We prove that D meson mixing occurs in the Standard Model only at second order in SU(3) violation. We…

The LHCb experiment has collected the world’s largest sample of charmed hadrons. This sample is used to measure observables related to D0 − D mixing, direct CP violation and CP violation in mixing…

A Review of CP Violation Measurements in Charm at LHCb

The LHCb experiment has been able to collect the largest sample ever produced of charm-hadron decays, performing a number of measurements of observables related to CP violation in the charm sector, including the most precise measurement of time-dependent CP asymmetry in D0→h+h− decays and the first observation of mass difference between neutral charm-meson eigenstates.

CP violation in $b$ and $c$ quark decays

Generically, non-Standard-Model particles contribute to processes with order-one charge-parity ( CP ) violating phases, as CP is not a fundamental symmetry of nature. The exploration of CP violation…

Sum rules for B^0 - \bar B^0 mixing at NLO of pQCD

The matrix element of B^0 -\bar B^0 mixing is evaluated from QCD sum rules for three-point correlators with next-to-leading order accuracy in pQCD.

Computing non-factorizable pQCD corrections to hadronic B^0 - \bar B^0 mixing matrix element within

In this talk I report on the results of a recent calculation of the \alpha_s corrections to a three-point correlation function at the three-loop level in QCD perturbation theory, which allows one to…

Width difference in the D0-anti-D0 system

The motivation most often cited in searches for D0-anti-D0 mixing lies with the possibility of observing a signal from new physics which dominates that from the Standard Model. We discuss recent…

Compilation of D0-D0bar Mixing Predictions

We present a compilation of predictions for the amplitudes of D 0 − D 0 mixing. We are not aware of any exhaustive compilation of predictions for the amplitudes for D 0 → D 0 . We have therefore…
