New CMS results on heavy flavour production and flavour anomalies
The CMS experiment has recently measured bottom quark hadronization fractions using 61.6 fb$^{-1}$ of proton-proton collisions at $\sqrt{s}=13$ TeV over a range of B hadron transverse momentum and rapidity, confirming the observed $p_T$ dependence of the ratio $f_s/f_u$ first measured by the LHCb e...

| description | The CMS experiment has recently measured bottom quark hadronization fractions using 61.6 fb$^{-1}$ of proton-proton collisions at $\sqrt{s}=13$ TeV over a range of B hadron transverse momentum and rapidity, confirming the observed $p_T$ dependence of the ratio $f_s/f_u$ first measured by the LHCb experiment. Additionally, a new measurement of the $B^0_s\rightarrow \mu^+\mu^-$ 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. |
