Search for nonresonant new physics in high-mass dilepton events in association with b-tagged jets /CMS Collaboration
A search for nonresonant new physics phenomena in high-mass dilepton events produced in association with b-tagged jets is performed using the data collected by the CMS experiment at the CERN LHC at a center-of-mass energy of $13~\mathrm{TeV}$. The analysis considers two EFT-based models with 6-dimensional operators involving four fermion contact interactions between two leptons (electrons and muons) and $\mathrm{b}$ or $\mathrm{s}$ quarks ($\mathrm{bb\ell\ell}$ and $\mathrm{bs\ell\ell}$).

Combination and interpretation of fiducial differential Higgs boson production cross sections at $\sqrt{s}=13~\mathrm{TeV}$ /CMS Collaboration
The Higgs boson fiducial differential production cross sections are sensitive probes for the presence of physics beyond the standard model. New physics may contribute to the gluon-gluon fusion loop, the dominant Higgs boson production mechanism at the LHC, and manifest itself as deviations from the expected standard model distributions.

Search for DM in association with b-quark and lepton pairs /CMS Collaboration
A search is performed for dark matter produced in association with bottom quark and lepton pairs in data collected by the CMS detector at the LHC, corresponding to $138~\mathrm{fb}^{-1}$ of proton-proton collisions at a center-of-mass energy of $13~\mathrm{TeV}$. The analysis explores for the first time at the LHC the associated production of a bottom quark-antiquark pair and a new neutral Higgs boson that subsequently decays into a Z boson and a pseudoscalar, where the latter acts as dark matter mediator in the context of the 2HDM+$a$ model.
