 Observation of the decay $\mathrm{Z}\to\psi\,\ell^+\ell^-\to\mu^+\mu^-\ell^+\ell^-$ with the CMS detector / Leontsinis, Stefanos (Zurich U.) /CMS Collaboration The observation of the $\mathrm{Z}$ boson rare decay to a $\psi$ meson and two oppositely charged same-flavour leptons, $\ell^+ \ell^-$, where $\psi$ represents the sum of $\mathrm{J}/\psi$ and $\psi(\mathrm{2S})\to\mathrm{J}/\psi\, X$, and $\ell=\mu,\mathrm{e}$, is presented. The data sample used corresponds to an integrated luminosity of $35.9\,\mathrm{fb}^{-1}$ of proton-proton collisions at a center-of-mass energy of $13\,\mathrm{TeV}$ accumulated by the CMS experiment at the LHC.

 Search for heavy neutral leptons (sterile neutrinos) with the CMS detector / Verbeke, Willem /CMS Collaboration The smallness of neutrino masses provides a tantalizing allusion to physics beyond the standard model (SM). Heavy neutral leptons (HNL), such as hypothetical sterile neutrinos, accommodate a way to explain this observation, through the see-saw mechanism.

 Measurement of the BEH scalar mass and other couplings in ATLAS and CMS / Sperka, David Michael (Florida U.) /ATLAS, CMS and Higgs collaborations The CMS and ATLAS collaborations have performed numerous studies of the Higgs boson's properties using $pp$ collisions from the LHC at $\sqrt{s}=13$ TeV during 2016. These studies include precision measurements of the Higgs boson's mass, which is a free parameter of the Standard Model. [...] CMS-CR-2018-036.- Geneva : CERN, 2018 - 7 p.

 Associated top production (ttV, tV) in ATLAS and CMS / Sánchez Cruz, Sergio /ATLAS and CMS Collaborations A set of measurements of top quark pair and single top quark production in association with standard model (SM) bosons performed by the CMS and ATLAS Collaborations is presented. The consistency of these results among themselves and with the SM prediction is discussed. [...] CMS CR-2018/033; CMS-CR-2018-033; arXiv:1805.02024.- Geneva : CERN, 2018 - 7 p.

 QCD Monte-Carlo model tuning studies with CMS data at 13 TeV / Sunar Cerci, Deniz (Cukurova U.) /CMS Collaboration New CMS PYTHIA 8 event tunes are presented. The new tunes are obtained using minimum bias and underlying event observables using Monte Carlo configurations with consistent parton distribution functions and strong coupling constant values in the matrix element and the parton shower.

 QCD probes at LHC / Da Silveira, G. Gil (Rio Grande do Sul U. ; Rio de Janeiro State U.) /ATLAS, CMS and LHCB Collaborations The LHC experiments have reported new results with respect to the dynamics of the strong interactions in $pp$, $p$A, and AA collisions over the past years. In proton-proton collisions, the data analyses have focused in exploring the nature of underlying events and double parton scattering at high energies.
