Search for top squark pair production in the dilepton final state using 137/fb of proton-proton collision integrated luminosity at sqrt(s) = 13 TeV /CMS Collaboration
A search for supersymmetric partners of the top quark is presented in final states with two oppositely charged leptons (electrons or muons), jets identified as originating from b quarks, and missing transverse momentum. The search uses data from proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ collected from 2016 to 2018 using the CMS detector, amounting to $137~\mathrm{fb}^{-1}$ of integrated luminosity.

MUSiC, a model unspecific search for new physics, in pp collisions at sqrt(s)=13 TeV /CMS Collaboration
Results of the Model Unspecific Search in CMS (MUSiC) using data recorded by the CMS detector at the LHC, during proton-proton collisions at a center of mass energy of $\sqrt{s}=13~\mathrm{TeV}$ in 2016 and corresponding to an integrated luminosity of $35.9~\mathrm{fb^{-1}}$, are presented. The MUSiC analysis aims to search for anomalies that could be probed as signatures for phenomena beyond the standard model, and is based on the comparison of data with the expectation according to the standard model, determined from simulations, in several hundred final states and multiple kinematic distributions.
