Résumé

We review four most precise measurements from charm physics program at the LHCb during 2021. These include the first observation of non-zero mass difference between neutral charm-meson eigenstates, the world most precise determination of both time-dependent and time-integrated charge-parity.

Precision measurement of neutral charm meson mixing parameters

Guillaume Max Pietrzyk

This thesis presents a measurement of the neutral charm meson mixing parameters

y_{C\!P}^{KK} - y_{C\!P}^{K\pi}

and

y_{C\!P}^{\pi\pi} - y_{C\!P}^{K\pi}

using

D^0 \rightarrow K^-K^+

D^0 \rightarrow \pi^-\pi^+

and

D^0 \rightarrow K^-\pi^+

decays. ...
