Measurement of rare $B \to \mu^+\mu^-$ decays with the Phase-2 upgraded CMS detector at the HL-LHC /CMS Collaboration
The sensitivity of the upgraded CMS detector for measuring the rare decays $B_{s}^0\to \mu^+ \mu^-$ and $B^0\to \mu^+ \mu^-$ in the HL-LHC scenario is studied. The upgraded detector, especially with its improved momentum resolution, and the foreseen total integrated luminosity of $3000~\mathrm{fb}^{-1}$ are expected to enable high precision measurements of the branching fractions of $B_{s}^0\to \mu^+ \mu^-$ and the effective lifetime of the $B_{s}^0\to \mu^+ \mu^-$ decay with reduced systematic and statistical uncertainties.

Search for an exotic decay of the Higgs boson to a pair of light pseudoscalars with two muons and two b jets in the final state at sqrts = 13 TeV /CMS Collaboration
A search for exotic decays of the Higgs boson to a pair of light pseudoscalar particles $\mathrm{a_1}$ is performed under the hypothesis that one of the pseudoscalars decays to a pair of opposite sign muons and the other decays to a $\mathrm{b}\mathrm{\overline{b}}$ pair. Such signatures are predicted in a number of extensions of the standard model (SM), including next-to-minimal supersymmetry and two-Higgs-doublet models with an additional scalar singlet. [...]
