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.

Inclusive nonresonant multilepton probes of new phenomena at $\sqrt{s}=13~\mathrm{TeV}$ /CMS Collaboration
An inclusive search for nonresonant signatures of beyond the standard model phenomena in events with three or more charged leptons, including hadronic decays of tau leptons, is presented. The analysis is based on a data sample corresponding to an integrated luminosity of $138~\mathrm{fb}^{-1}$ of proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$, collected with the CMS detector at the LHC in $2016-2018$.

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.
