The beauty and charm of fast and slow neutral meson oscillations at LHCb

<!--HTML--><p class="MsoPlainText"><span><span>The superposition of flavour (and mass) eigenstates of neutral mesons is a stunning example of quantum mechanics in the Standard Model. The phenomenological consequence is a small mass difference between the mass eigenstates, and time-dependent oscillations of the flavour eigenstates. In this seminar the legacy measurement of the mass difference (delta-ms) in the B0s system is shown and a significant new result for the D0 system will be reported.</span></span></p> LHC Seminar - LHCb: https://cern.zoom.us/j/61942619819?pwd=Q1ZrVTBnSWdsNThsVVF2NHVZbWFoZz09
