 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.

 Experimental results using the decay of the Higgs to taus and muons / Meyer, Mareike (DESY) /ATLAS and CMS Collaborations Precise measurements of the Higgs boson Yukawa couplings provide important tests of the Standard Model of particle physics. This review summarizes the current status of the analyses performed by the ATLAS and CMS experiments that search for the Higgs boson decay into a pair of muons.

 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..

 Measurements of the Yukawa couplings of the Higgs boson at CMS / Missiroli, Marino (DESY) /CMS Collaboration The latest results on the measurement of the Higgs boson couplings to fermions with the CMS detector are reported. Most of these results are based on proton-proton collisions data at $\sqrt{s}=13~\text{TeV}$ recorded in 2016 for an integrated luminosity of $35.9~\text{fb}^{-1}$; in some cases, the combination with Run-1 data at $\sqrt{s}=7~\text{TeV}$ and $\sqrt{s}=8~\text{TeV}$ is also included.

 Design and object performance of the CMS High Granularity Calorimeter Level 1 trigger / Strebler, Thomas (Imperial Coll., London) /CMS Collaboration The high luminosity (HL) LHC will pose significant detector challenges for radiation tolerance and event pileup, especially for forward calorimetry, and this will provide a benchmark for future hadron colliders. The CMS experiment has chosen a novel high granularity calorimeter (HGCAL) for the forward region as part of its planned Phase 2 upgrade for the HL-LHC.

 Latest results on VBF and VBS processes from CMS experiment / Chernyavskaya, Nadezda (Zurich, ETH) /CMS Collaboration The latest measurements of the Vector Boson Fusion (VBF) and Vector Boson Scattering (VBS) processes from the CMS experiment are presented, using 36~\fb data collected in proton-proton collisions at $\sqrt{s}$ = 13 TeV at the LHC. The measured total cross sections are compared to the theoretical predictions and limits are set on the presence of anomalous triple and quartic gauge couplings..

 Calorimetry at very forward rapidity / Scott, Edward John Titman (Imperial Coll., London) /CMS Collaboration The CMS experiment at CERN will undergo significant improvements during the so-called Phase-II Upgrade to cope with a 10-fold increase in integrated luminosity with the High Luminosity LHC (HL-LHC) era. A particularly challenging environment is the forward region, where the combination of extremely high radiation levels (fluence and ionising dose) coupled with up to 200 simultaneous pileup events necessitates new technologies and methodologies.

 Upgrades of the CMS muon system in preparation of HL-LHC / Guiducci, Luigi (INFN, Bologna ; Bologna U.) /CMS Collaboration The present CMS muon system operates three different detector types: barrel drift tubes (DT) and resistive plate chambers (RPC), along with cathode strip chambers (CSC) and another set of RPCs in the forward regions. In order to cope with increasingly challenging conditions, various upgrades are planned to the trigger and muon systems. [...] CMS-CR-2018-184.- Geneva : CERN, 2018 - 6 p.

 Projected performance of CMS Cathode Strip Chambers at HL-LHC / Joshi, Bhargav Madhusudan (Florida U.) /CMS Collaboration Cathode Strip Chambers (CSC) are a crucial component of the CMS endcap muon system which will operate throughout the lifetime of the LHC and beyond, during the HL-LHC running. We present an analysis of the expected CSC performance in a HL-LHC like environment as well as studies of CSC detector longevity over the lifetime of the HL-LHC..

 Machine learning techniques for heavy flavour identification / Chazin Quero, Barbara (Cantabria Inst. of Phys.) /CMS Collaboration Reliable and performant heavy flavour identification is of prime importance for the physics program of the CMS experiment. During the last years the CMS collaboration has dedicated a considerable effort to improve and expand its capabilities in this sector by applying several machine learning techniques well established in industry, but still experimental in HEP.
