New CMS results on heavy flavour production and flavour anomalies

The CMS experiment has recently measured bottom quark hadronization fractions using 61.6 /fb of proton-proton collisions at a center-of-mass energy of 13 TeV over a range of B hadron transverse momentum and rapidity, confirming the observed pT dependence of the ratio fs/fu first measured by the LHCb experiment. Additionally, a new measurement of the Bs0->mu+mu- branching fraction by CMS is described which is in closer agreement with the standard model than previous results based on the 2020 combination of ATLAS, LHCb, and CMS analyses.
