 Search for heavy BSM particles coupling to third generation quarks at CMS / Meyer, Mareike (Hamburg U.) /CMS Collaboration Many models of physics beyond the Standard Model (SM) contain enhanced couplings to third generation particles. The predicted signatures include vector-like quarks and ttbar resonances. [...] CMS-CR-2017-205.- Geneva : CERN, 2017 - 11 p.

 Top quark event modelling and generators in CMS / Yazgan, Efe (Beijing, Inst. High Energy Phys.) /CMS Collaboration Recent top quark event modelling studies done using CMS proton-proton data collected at a centre of mass energies of 8 and 13 TeV and state-of-the-art theoretical predictions accurate to next-to-leading order QCD interfaced with PYTHIA and HERWIG event generators are summarised. The particle-level top quark (pseudo-top), underlying event measurement in \ttbar events and parton shower tuning using \ttbar events are discussed.. CMS-CR-2017-204.- Geneva : CERN, 2017 - 6 p.

 Search for SM deviations in top precision studies at CMS / Skovpen, Kirill (Vrije U., Brussels) /CMS Collaboration Precision studies of top quark properties provide a unique playground to test the predictions of the standard model and to search for new physics. Reviewed results from the CMS experiment done with the data collected at 8 TeV include studies of top quark Wtb anomalous and FCNC couplings, polarization, CP-violation and spin correlation effects.

 Pixel Detector Developments for Tracker Upgrades of the High Luminosity LHC / Meschini, Marco (INFN, Florence) ; Boscardin, M ; Dalla Betta, G. F ; Dinardo, Mauro (INFN, Milan Bicocca ; Milan Bicocca U.) ; Giacomini, G ; Menasce, Dario (INFN, Milan Bicocca) ; Mendicino, R ; Messineo, Alberto (INFN, Pisa ; Pisa U.) ; Moroni, Luigi (INFN, Milan Bicocca) ; Ronchin, S et al. This paper reports on the INFN (Istituto Nazionale di Fisica Nucleare, Italy) research activity in collaboration with FBK foundry, which is aiming at the development of new pixel detectors for the LHC Phase-2 upgrades. The R\&D; covers both planar pixel devices and 3D detectors built using columnar technology. All sensors are low thickness n-in-p type, as this is the general direction envisaged for the High Luminosity LHC pixel detector upgrades. [...] CMS-CR-2017-190.- Geneva : CERN, 2017 - 8 p.

 Production and quality control of GEM detectors for the Phase 1 upgrade of the CMS experiment / Soldani, Elisabetta (INFN, Bari ; Bari U.) /CMS Collaboration The CMS collaboration has approved the installation of an additional set of muon detectors based on triple-GEM technology in the first endcap muon station known as GE1/1 [1]. They will be installed in 2019 during the second Long Shutdown (LS2) planned by LHC. [...] CMS-CR-2017-185.- Geneva : CERN, 2017 - 3 p.

 The INFN R\&D: new pixel detector for the High Luminosity Upgrade of the LHC / Dinardo, Mauro (INFN, Milan Bicocca ; Milan Bicocca U.) ; -FBK Pixel RandD Collaboration /ATLAS and CMS Collaborations The High Luminosity upgrade of the CERN-LHC (HL-LHC) demands for a new high-radiation tolerant solid-state pixel sensor capable of surviving fluencies up to a few $10^{16}$~ particles/cm$^2$ at $\sim$3~cm from the interaction point. To this extent the INFN ATLAS-CMS joint research activity, in collaboration with Fondazione Bruno Kessler-FBK, is aiming at the development of thin n-in-p type pixel sensors for the HL-LHC.

 Is Nature Standard like the Model? Experimental results on Standard Model and Higgs boson physics / Massironi, Andrea (Northeastern U.) /CMS Collaboration Recent results on Standard Model and Higgs boson measurements performed by ATLAS and CMS collaborations will be reported. The presentation will include results based on LHC Run II data, with particular relevance on most recent ones. [...] CMS-CR-2017-168.- Geneva : CERN, 2017 - 7 p.

 Very forward inclusive jet cross sections in p+Pb collisions at 5\,TeV at CMS / Van De Klundert, Merijn H F (Antwerp U.) /CMS Collaboration Very forward inclusive jet energy spectra were measured with the CMS experiment at the LHC in proton-lead collisions, with a centre-of-mass energy of $\sqrt{s_{\mathrm{NN}}}=5.02\,\mathrm{TeV}$. The measurement was performed using the CASTOR calorimeter, which measures in the pseudorapidity range $-6.6<\eta<-5.2$. [...] CMS-CR-2017-183.- Geneva : CERN, 2017 - 7 p.

 Commissioning of the Phase-1 upgrade of the CMS pixel detector / Vormwald, Benedikt Roland (Hamburg U.) The Phase-1 upgrade of the CMS pixel detector is built out of four barrel layers (BPIX) and three forward disks in each endcap (FPIX). It comprises a total of 124M pixel channels in 1856 modules and it is designed to withstand instantaneous luminosities of up to $2\times10^{34}\,\mathrm{cm}^{-2}\mathrm{s}^{-1}$.
