Search for heavy scalar resonances decaying to a pair of Z bosons in the 4-lepton final state at 13 TeV /CMS Collaboration
A search for a heavy scalar resonance decaying to two Z bosons and subsequently to four leptons is presented, where the leptons can be electrons or muons. The results are based on the proton-proton collision data collected by the CMS experiment at the LHC at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 $\text{fb}^{-1}$.

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.

Search for vector-like leptons with long-lived particle decays in the CMS muon system /CMS Collaboration
This note presents a search for vector-like leptons (VLLs), which in turn decay into a long-lived pseudoscalar and a standard model tau lepton. The pseudoscalar with a mass of 2 GeV exclusively decays into a pair of photons, and is identified using the muon detector shower signature. [...]

Measurement of the inclusive WZ production cross section in pp collisions at $\sqrt{s}=13.6~\mathrm{TeV}$ with the CMS experiment /CMS Collaboration
The inclusive WZ cross section is measured in proton-proton collisions at a centre-of-mass energy of $13.6~\mathrm{TeV}$, using $34.7~\mathrm{fb}^{-1}$ of data collected during 2022 with the CMS detector. The measurement is performed in multileptonic final states by performing a simultaneous likelihood fit to the number of events in four different lepton flavour categories: $\mathrm{eee}$, $\mathrm{ee}{\mu}$, ${\mu}{\mu}\mathrm{e}$, ${\mu}{\mu}{\mu}$.
