Measurement of the inclusive and differential $\text{t}\bar{\text{t}}\gamma$ cross section and EFT interpretation in the dilepton channel at $\sqrt{s}=13\,\text{TeV}$ /CMS Collaboration
The production cross section of a top quark pair in association with a photon is measured in pp collisions in the decay channel with two oppositely charged leptons ($\text{e}^\pm\mu^\mp$, $\text{e}^+\text{e}^-$, $\mu^+\mu^-$). The data set of $138\,\text{fb}^{-1}$ was recorded by the CMS experiment at $\sqrt{s}=13\,\text{TeV}$ during the 2016 to 2018 data-taking period of the CERN LHC. [...]

A new set of CMS tunes for novel colour reconnection models in PYTHIA8 based on underlying-event data /CMS Collaboration
New sets of parameter tunes for two of the colour reconnection models implemented in the PYTHIA8 event generator, QCD-inspired and gluon move, are obtained based on the default CMS PYTHIA8 underlying-event tune, CP5. Measurements sensitive to underlying-event performed at $\sqrt{s}=$1.96, 7, and 13$~\mathrm{TeV}$ are used to constrain the parameters of the colour reconnection models and the multiple parton interactions simultaneously.

Search for heavy resonances and quantum black holes in e$\mu$, e$\tau$, and $\mu\tau$ final states in proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ /CMS Collaboration
A search is reported for heavy resonances and quantum black holes decaying into e$\mu$, e$\tau$, and $\mu\tau$ final states in proton-proton collisions recorded by the CMS experiment at the CERN LHC at $\sqrt{s}=13~\mathrm{TeV}$, corresponding to an integrated luminosity of $137.1~\mathrm{fb}^{-1}$. No evidence is found for physics beyond the standard model in the dilepton invariant mass spectra, and upper limits are set at $95\%$ confidence level on the products of the cross sections and branching fractions for various lepton-flavor violating signals.
