About
Rare B meson decays proceeding via flavour-changing neutral currents allow precision tests of the Standard Model and provide a sensitive probe for potential beyond-the-Standard-Model contributions. In this seminar, we present a new measurement of the Bs → μ+μ− branching fraction and effective lifetime, as well as results of a search for the B0 → μ+μ− decay. The analysis is based on pp collision data collected by the CMS experiment at sqrt(s)=13 TeV during the LHC Run 2, corresponding to an integrated luminosity of 140 fb−1.
