 Long-term aging studies on Resistive Plate Chambers (RPC) of the CMS muon system for HL-LHC / Gelmi, Andrea (INFN, Bari ; Bari U.) /CMS Collaboration During the phase II of the LHC physics program, called High Luminosity LHC (HL-LHC), the accelerator will increase the instantaneous luminosity up to 5$\times$10$^{34}$cm$^{-2}$s$^{-1}$, providing to experiments an additional integrated luminosity of about 3000 fb$^{-1}$ over 10 years of operation, starting in 2026. The present Compact Muon Solenoid (CMS) Resistive Plate Chambers (RPC) system has been certified for 10 LHC years operation, at maximum background rate of 300 Hz/cm$^{2}$ and 50 mC/cm$^{2}$ as integrated charge.

 Geant4 simulation of a Triple-GEM detector exposed to the CHARM field at CERN / Vai, Ilaria (INFN, Pavia ; Pavia U.) /CMS Collaboration The ME0 station has been proposed for the installation in the CMS muon system in the region $2.03 < \vert \eta \vert < 2.82$, with the aim of increasing the detector acceptance for physics with muons. This region, presently not instrumented, is characterized by a very harsh radiation environment, which can reach rates up to 30 kHz/cm$^2$ and an integrated charge of the order of 200 mC/cm$^2$ over ten years of operation.

 Search for Vector Like Quarks by CMS / Beauceron, Stephanie (Lyon, IPN) /CMS Collaboration We present results of searches for massive vector-like top and bottom quark partners using proton-proton collision data collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV. Single and pair production of vector-like quarks are studied, with decays into a variety of final states, containing top and bottom quarks, electroweak gauge and Higgs bosons.

 Design, Construction and Commissioning of the Upgrade Radiation Damage Monitoring System of the CMS Hadron Forward Calorimeters / Onel, Yasar (Iowa U.) /CMS Collaboration The CMS Hadron Forward Calorimeters cover pseudorapidities between 3.0 and 5.0 being exposed to the highest radiation levels in the CMS detector system. The calorimeter consists of quartz fibers as active media inserted into the steel absorber structure. [...] CMS-CR-2018-413.- Geneva : CERN, 2018 - 5 p.

 Exotics at the LHC / Del Re, Daniele (INFN, Rome ; Rome U.) /ATLAS, CMS and LHCB Collaborations LHC has worked beautifully and provided more than 100 fb$^{-1}$ at 13 TeV. Thanks to this enormous statistics of p-p collisions, LHC experiments have been able to explore several different new physics scenarios. [...] CMS-CR-2018-392.- Geneva : CERN, 2018 - 11 p.

 Top pair production measurements, inclusive and differential / Fernandez Menendez, Javier (Oviedo U.) /ATLAS, CMS and LHCB Collaborations Recent results and state-of-the-art on top-quark pair production cross sections in both inclusive and differential measurements are presented, obtained using data collected with the ATLAS, CMS and LHCb experiments during the LHC Run1 and Run2 periods up to the year 2016 at centre-of-mass energies ranging from 5.02 to 13TeV. Results are confronted against Standard Model (SM) next-to-leading order (NLO) and next-to-next-to-leading order (NNLO) predictions, several Monte Carlo (MC) generators and tunes, and parton density function variations, with a special focus on the latest Run2 results..

 Top quark properties / Van Mulders, Petra Karel Ann (Vrije U., Brussels) /ATLAS and CMS Collaborations The multi-purpose experiments at CERN's Large Hadron Collider have a very rich programme in top quark physics. The large amount of data allows for measuring the top quark properties with an unprecedented precision. [...] CMS-CR-2018-284.- Geneva : CERN, 2018 - 6 p.

 Top quark mass measurement in the $\mathrm{t\bar{t}}$ all-jets final state with the CMS experiment at $\sqrt{s}=13\,\mathrm{TeV}$ / Lange, Johannes (Hamburg U.) /CMS Collaboration The top quark mass is measured using $35.9~\mathrm{fb}^{-1}$ of LHC proton-proton collision data collected with the CMS detector at $\sqrt{s}=13~\mathrm{TeV}$ in 2016. The measurement uses the $\mathrm{t}\overline{\mathrm{t}}$ all-jets final state, which comprises a total of six jets. [...] arXiv:1812.05394; CMS-CR-2018-386.- Geneva : CERN, 2018 - 5 p.
