 Search for heavy neutral leptons, right-handed neutrinos and long-lived particles with the CMS detector / Negro, Giulia (IRFU, Saclay) /CMS Collaboration A selection of recent CMS results on heavy neutral leptons, right-handed neutrinos and long-lived particles is reported. The search for heavy neutral leptons in the trilepton channel and in the same-sign dilepton channel, the search of a $W_R$ decaying into two leptons and two jets through a right-handed neutrino, and the searches on stopped long-lived particles and disappearing tracks are presented..

 Search for leptoquarks in CMS / Takahashi, Yuta (Zurich U.) /CMS Collaboration Leptoquarks (LQs) are hypothetical bosons, each coupling to a lepton and a quark of a given generation. They recently got particular attention, as the TeV-scale LQ'' might explain observed anomalies reported by dedicated B physics experiments. [...] CMS-CR-2018-049.- Geneva : CERN, 2018 - 7 p.

 Search for Dark Matter in final states with top quarks in CMS data / Kevin Kai Hong Sung /CMS Collaboration Searches for dark matter (DM) produced in association with a single top quark or a top quark pair in proton-proton collisions at $\sqrt{s}$ = 13 TeV are presented. The data corresponds to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$ recorded by the CMS detector at the CERN LHC in 2016. [...] CMS-CR-2018-047.- Geneva : CERN, 2018 - 7 p.

 SUSY searches in the context of R-parity violation with CMS data / Seitz, Claudia (Zurich U.) /CMS Collaboration Several searches for supersymmetric particles are presented using data collected by the CMS experiment during Run 2 of the LHC. With rather stringent limits placed on R-parity conserving models, we explore three different scenarios where R-parity is not conserved. In these cases the lightest supersymmetric particle is not required to be stable, and can decay exclusively into known standard model particles. Different coupling scenarios and coupling strengths are possible, however, the focus here lies on prompt hadronic R-parity violating decays.. CMS-CR-2018-035.- Geneva : CERN, 2018 - 8 p.

 Search for exotic Higgs boson decays to pairs of light pseudoscalars with the CMS detector / Caillol, Cecile (Wisconsin U., Madison) /CMS Collaboration Searches for exotic Higgs boson decays to pairs of light pseudoscalars are performed using the data collected by the CMS experiment at center-of-mass energies of 8 and 13 TeV. The results are interpreted in different scenarios of two Higgs doublet models extended by a scalar singlet. [...] CMS-CR-2018-030.- Geneva : CERN, 2018 - 7 p.

 CMS Higgs boson results / Bluj, Michal Jacek (NCBJ, Swierk) /CMS Collaboration In this report we review recent Higgs boson results obtained with pp collisions at $\sqrt{s}=\,$13 TeV recorded by the CMS detector in 2016 for an integrated luminosity of 35.9fb$^{\text{-1}}$. The 2016 data allowed the observation of the $H \to \tau\tau$ and $H \to WW$ decays with high significance. [...] CMS-CR-2018-045.- Geneva : CERN, 2018 - 5 p.

 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.
