 Operation and Performance of a new microTCA-based CMS Calorimeter Trigger in LHC Run 2 / Klabbers, Pamela Renee (Wisconsin U., Madison) /CMS Collaboration The Large Hadron Collider (LHC) at CERN is currently increasing the instantaneous luminosity for p-p collisions. In LHC Run 2, the center-of-mass energy has gone from 8 to 13 TeV and the instantaneous luminosity will approximately double for proton collisions. [...] CMS-CR-2016-428.- Geneva : CERN, 2016 - 5 p.

 Measurement of differential and integrated fiducial cross sections for Higgs boson production in the four-lepton decay channel in pp collisions at $\sqrt{s} = 7, 8$ and $13$~TeV / Ahmad, Muhammad (Beijing, Inst. High Energy Phys.) /CMS Collaboration Integrated fiducial cross sections for the production of four leptons via the $H \rightarrow 4\ell$ decays ($\ell = e, \mu$) are measured in pp collisions at $\sqrt{s} = 7, 8$ and $13$~TeV. Measurements are performed with data corresponding to integrated luminosities of 5.1 fb${}^{-1}$ at $\sqrt{s}=7$~TeV, 19.7 fb${}^{-1}$ at $\sqrt{s}=8$~TeV and 12.9 fb${}^{-1}$ at $\sqrt{s}=13$~TeV, collected with the CMS experiment at the LHC.

 Search for new physics with tau final states at 13 TeV / Mao, Zaixing (Brown U.) /CMS Collaboration Searches for four new particles: Sequential Standard Model W' and Z' bosons, right-handed W bosons and third-generation leptoquarks; are performed using pp collision data at $\sqrt{s} = 13$ TeV recored by the CMS detector at the LHC. The events observed are found to be in good agreement with the SM predictions. [...] CMS-CR-2016-390.- Geneva : CERN, 2016 - 5 p.

 Studies of tt+V at CMS / Khvastunov, Illia (Gent U.) /CMS Collaboration A measurement of the production cross-section of a pair of top quarks in association with a photon, using 19.7 $fb^{-1}$ of pp collision data collected by CMS detector at $\sqrt{s} =$ 8 TeV, and with W and Z boson, using 12.9 $fb^{-1}$ of data collected at $\sqrt{s} =$ 13 TeV, is presented. The measurement of t$\bar{\text{t}}\gamma$ is performed in in the fiducial phase space corresponding to the semileptonic decay chain of the top quark pair, and the cross section is measured relative to the inclusive top quark pair production cross section.

 Readout electronics and test bench for the CMS Phase I pixel detector / Del Burgo, Riccardo (Zurich U.) /CMS Collaboration The present CMS pixel detector will be replaced with an upgraded pixel system during the LHC extended technical stop in winter 2016/2017. The CMS Phase 1 pixel upgrade combines a new pixel readout chip, which minimizes detection inefficiencies, with several other design improvements to maintain the excellent tracking performance of CMS at the higher luminosity conditions foreseen for the coming years.

 Studies of the ttH production at 13 TeV / Cirkovic, Predrag (VINCA Inst. Nucl. Sci., Belgrade) /CMS Collaboration In this talk, the latest results of searches for the standard model Higgs boson produced in association with a top quark-antiquark pair ($t\bar{t}H$), where Higgs decays into photons, bottom quark-antiquark pair or leptons via WW, ZZ and $\tau\tau$ will be presented. The analyses have been performed using the $13\,TeV$ pp collisions data recorded by the CMS experiment in 2015 and part of 2016. [...] CMS-CR-2016-304.- Geneva : CERN, 2016 - 9 p.

 Commissioning of Upgrade Forward Hadron Calorimeters of CMS / Bilki, Burak (Iowa U.) /CMS Collaboration The CMS experiment at the Large Hadron Collider (LHC) at CERN is upgrading the photo-detection and readout system of the forward hadron calorimeter (HF). During Long Shutdown 1, all of the original PMTs were replaced with multi-anode, thin window photomultipliers. [...] CMS-CR-2016-417.- Geneva : CERN, 2016 - 5 p.

 The phase-1 upgrade of the CMS pixel detector / Weber, Hannsjorg Artur (Fermilab) /CMS Collaboration The pixel detector of the CMS experiment will be upgraded during the extended end of year shutdown during winter 2016/2017. The upgraded detector will operate at full efficiency at an instantaneous luminosity of ${2\times10^{34}}$\,cm$^{{-2}}$s$^{{-1}}$ with increased detector acceptance and additional redundancy for the tracking, while at the same time reducing the material budget.

 Measurement of the differential cross section for top-quark-pair production in the dilepton channel at $\sqrt{s}$ = 13 TeV with the CMS detector / Savitskyi, Mykola (DESY) /CMS Collaboration Measurements of normalized differential top-quark-pair ($t\bar{t}$) production cross sections are performed using final states with two leptons ($e^+e^-$, $\mu^+\mu^-$, and $e^\pm\mu^\mp$) in proton-proton ($pp$) collisions at $\sqrt{s}$ = 13 TeV at the CERN LHC. The data were recorded in 2015 with the CMS detector and correspond to an integrated luminosity of 2.2 fb$^{-1}$. [...] CMS-CR-2016-423.- Geneva : CERN, 2016 - 6 p.
