Mixing and indirect CP violation in charm decays at LHCb
September 13, 2021
The very large datasets of charm decays collected by the LHCb experiment from 2011 to 2018 allow the measurement of the mixing and charge-parity ($C\!P$) violation properties of $D^0$ mesons with unprecedented precision. This document covers two recent analyses studying mixing and time-dependent $C\!P$ violation in charm decays at LHCb. The first analysis presents the world's most precise determination of the $C\!P$ violation parameter $\Delta Y$, while the second accounts for the first observation of the mass difference between neutral charm-meson eigenstates.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
