 Electroweak boson production with jets at CMS / Sandeep, Kaur (Panjab U.) /CMS Collaboration The differential cross sections measurement for a W/Z boson produced in association with jets is presented. The measurement is based on 13 TeV proton-proton collision data corresponding to an integrated luminosity of 2.2 fb$^{-1}$, recorded by the Compact Muon Solenoid (CMS) detector at the LHC during run II in 2015.

 Recent CMS results of the Higgs boson produced in association with top quarks / El Morabit, Karim (KIT, Karlsruhe, EKP) /CMS Collaboration The associated production of a Higgs boson with a top quark-antiquark pair ($\rm t\bar{t}H$) or with a single top quark ($\rm tH$) allows the direct measurement of the top-Higgs-Yukawa coupling. In this article recent searches for $\rm t\bar{t}H$ and $\rm tH$ production at the CMS experiment are reviewed. [...] CMS-CR-2018-187.- Geneva : CERN, 2018 - 7 p.

 Single top quark production at CMS / Palencia Cortezon, Jose Enrique (Oviedo U.) /CMS Collaboration The most recent measurements of single top quark production in proton-proton collisions at the LHC at centre-of-mass energies of 7, 8 and 13 TeV, using data collected with the CMS experiment, are presented. Precise measurements of the single top production cross section in the two most dominant production modes (t channel and tW production), measurements of rare processes involving a top quark and a neutral electroweak boson (Z or photon), and searches for Flavour changing neutral currents are discussed..

 Hunting for narrow resonances in the dijet mass spectrum at CMS / Diamantopoulou, Melpomeni (Athens U.) /CMS Collaboration Results from the Dijet Resonance Search using data from 2016 and 2017 running will be shown, with emphasis on narrow resonances, for resonance masses above 1.6 TeV and a variety of new physics models used for the interpretation of the experimental results. The traditional method of estimating the QCD background is used, employing a parametrization for the background and an empirical fit of the data in the signal region..

 Searches for long-lived particles with CMS / Kutzner, Viktor Gerhard (Hamburg U.) /CMS Collaboration The current status of the searches for exotic, long-lived particles with the CMS experiment at $\sqrt{s}=13$~TeV is presented. Many theories beyond the Standard Model predict long-lived particles, for which different search approaches are utilized from those used in prompt searches.

 Search for Z' gauge boson predicted by lepton flavor and lepton flavor universality violating models with the CMS experiment at LHC / Kalsi, Amandeep Kaur (Brussels U.) /CMS Collaboration The standard model conserves lepton flavor and lepton flavor universality although these do not follow from an underlying gauge symmetry. However, the discovery of neutrino oscillations and anomalies observed in B-meson decays indicate violation of lepton flavor and lepton flavor universality, respectively.

 Precision Timing with the CMS MIP Timing Detector / Pena, Cristian (Fermilab) /CMS Collaboration The Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is undergoing an extensive Phase II upgrade program to prepare for the challenging conditions of the High-Luminosity LHC (HL-LHC). A new timing layer is designed to measure minimum ionizing particles (MIPs) with a time resolution of ~30ps and hermetic coverage up to a pseudo-rapidity of $\vert \eta \vert$ = 3.

 New results on collectivity in small systems with CMS / Milosevic, Jovan (VINCA Inst. Nucl. Sci., Belgrade) /CMS Collaboration The elliptic ($\upsilon_{2}$) flow of prompt D$^{0}$ mesons, together with K$^{0}_{S}$, $\Lambda$, $\Xi$, and $\Omega$ in high-multiplicity pPb collisions at 8.16~TeV, is presented. The data are collected with the CMS detector at the LHC from the rapidity interval $-1.46 < y_{cm} < 0.54$ and transverse momentum range 1.5 $< \mathrm{p_{T}} <$ 8~GeV.

 SEARCHES FOR DARK MATTER PARTICLES AT THE LHC / Felcini, Marta (University Coll., Dublin) /ATLAS ,CMS and SUSY Collaborations The searches for new particles that could be constituents of the dark matter in the universe are an essential part of the physics program of the experiments at the Large Hadron Collider. An overview of recent dark matter candidate searches is presented with a focus on new results obtained by the ATLAS and CMS experiments from the analysis of the proton-proton collision data at 13 TeV center-of-mass energy collected in the first part of Run 2.. arXiv:1809.06341; CMS-CR-2018-176.- Geneva : CERN, 2018 - 10 p.
