Search for stop pair production in di-tau final states (full Run 2) /CMS Collaboration
A search for pair production of the supersymmetric partner of the top quark, the top squark, in proton-proton collision events at $ \sqrt{s} = 13$ TeV is presented in final states containing at least one hadronically decaying tau lepton and large missing transverse momentum. This final state is highly sensitive to high-$\tan\beta$ or higgsino-like scenarios in which decays of electroweakinos to tau leptons are dominant. [...]

Measurements of simplified template cross sections and inclusive signal strengths are presented for the production of a 125 GeV Higgs boson decaying into a pair of b quarks, produced in association with a vector boson. The analysis is based on the leptonic decays of the W and Z bosons, resulting in final states with 0, 1, or 2 electrons or muons. [...]

Search for Higgs boson decays to invisible particles produced in association with a top-quark pair or a vector boson in proton-proton collisions at \texorpdfstring{$\sqrt{s}=13~\mathrm{TeV}$} and combination across Higgs production modes /CMS Collaboration
A search for Higgs boson decays to invisible particles, produced in association with a top quark pair or a vector boson decaying in a fully hadronic final state, has been performed using $138~\mathrm{fb^{-1}}$ of proton-proton collision data collected at $\sqrt{s}=13~\mathrm{TeV}$ by the CMS experiment at the LHC. Events are categorized based on jet multiplicity, the number of jets stemming from b quark decays as well as the number of hadronically decaying boosted top quarks and W bosons reconstructed as a single large-cone jet in the detector.
