11:30 → 13:00 Recent heavy flavour results from CMS¶

Abstract:
The CMS experiment has delivered numerous significant measurements using data from LHC Run-2 and the ongoing Run-3. This report explains key components of the CMS detector relevant to heavy flavour physics. The short introduction to CP violation in Bs → J/ψϕ(1020) is given, followed by the recent CMS results, confirming the CP violation in this channel. The search for CP violation in Ds → Ks0 Ks0 channel is presented. In addition the most important information on selected recent CMS heavy flavour physics results is highlighted. It includes: measurement of Bs → J/ψKS effective lifetime, test of lepton flavour universality with RJ/ψ and search for rare decays in D0 → µ+ µ− . Finally the CMS measurements of B/Bs → µ+ µ− are reminded.
