 The Phase-1 Upgrade of the CMS Pixel Detector / Lipinski, Martin (Aachen, Tech. Hochsch.) /CMS Collaboration The innermost tracking device of the CMS experiment is a silicon pixel detector. It has to cope with high particle fluxes and radiation damage, and was built to withstand the LHC design luminosity of 1$\times10^{34}$ cm$^{-2}$s$^{-1}$.

 Top quark physics at CMS / Lontkovskyi, Denys (Vrije U., Brussels) /CMS Collaboration Top quark production cross sections and properties are studied at different centre of mass energies in proton-proton collisions in the CMS experiment at the LHC. The recent results include total and differential top cross sections, mass determinations and searches for rare standard model and new physics processes involving top quarks..

 Electronics for CMS Endcap Muon Level-1 Trigger System Phase-1 and HL LHC Upgrades Summary / Madorsky, Alexander (Florida U.) /CMS Collaboration To accommodate high-luminosity LHC operation at 13 TeV collision energy, the CMS Endcap Muon Level-1 Trigger system had to be significantly modified. To provide the best track reconstruction, the trigger system must now import all available trigger primitives generated by Cathode Strip Chambers and by certain other subsystems, such as Resistive Plate Chambers (RPC).

 Heavy flavour production and properties at ATLAS and CMS / Galanti, Mario (Rochester U.) /ATLAS and CMS Collaborations The ATLAS and CMS experiments have carried out a rich heavy flavor physics program since the start of LHC data taking. In the current note some of the most recent results obtained by the two collaborations are shown. [...] CMS-CR-2017-140.- Geneva : CERN, 2017 - 5 p.

 $\text{t}\overline{\text{t}}$(+x) pair production at CMS and ATLAS / Beck, Lana Margaret Gwen (Bristol U.) /ATLAS ,CMS and Top Collaborations After a successful Run 1 in which the top quark was rediscovered and analysed, Run 2 is underway with many top quark analyses produced on the initial datasets collected. CMS and ATLAS have both collected $\approx40~$fb$^{-1}$ of data at this time, with much of it still to be analysed. [...] CMS-CR-2017-142.- Geneva : CERN, 2017 - 5 p.

 Standard model and heavy-ion physics at ATLAS and CMS / Gallo, Elisabetta (DESY) /ATLAS and CMS Collaborations Recent highlights on standard model results from the ATLAS and CMS Collaborations at the LHC are presented. The results cover W and Z physics, top quark production and jets cross sections. [...] CMS-CR-2017-138.- Geneva : CERN, 2017 - 15 p.

 A new design using GEM-based technology for the CMS experiment / Ressegotti, Martina (INFN, Pavia) The muon system of the Compact Muon Solenoid (CMS) experiment at the LHC is currently not instrumented for pseudorapidity higher than abs(${\eta}$)${ > 2.4}$. The main challenges to the installation of a detector in that position are the high particle flux to be sustained, a high level of radiation, and the ability to accomodate a multilevel detector into the small available space (less than 30 cm).

 Progress with electroweak-ino searches with 13 TeV data / Marionneau, Matthieu (Zurich, ETH) /ATLAS and CMS Collaborations Recent results from searches for production of supersymmetric partner of electroweak bosons are presented, using 13 to 36 fb$^{-1}$ 13 TeV data sets collected by the ATLAS and CMS experiments in 2016. The various results are interpreted in simplified SUSY models.No signal of physics beyond the Standard Model has been observed so far.. CMS-CR-2017-120.- Geneva : CERN, 2017 - 7 p.

 Measurements of $\phi_{\textrm{s}}$ and other related quantities, e.g. penguin pollution / Behera, Prafulla (Indian Inst. Tech., Madras) /CMS Collaboration The decay $\textrm{B}_{\textrm{s}}^{0} \to \textrm{J}/\psi \phi(1020) \to \mu^{+}\mu^{-}K^{+}K^{-}$ is used to measure the CP-violating weak phase $\phi_{\textrm{s}}$ and the decay width difference $\Delta \Gamma_{\textrm{s}}$ of the B$_{\textrm{s}}^{0}$\ light and heavy mass eigenstates with the CMS detector at the LHC. The analysis is performed using an integrated luminosity of 19.7 fb$^{-1}$ collected in pp collisions at a centre-of-mass energy of 8 TeV corresponds to a total of 49 200 reconstructed B$_{s}^{0}$ decays [...] CMS-CR-2017-092.- Geneva : CERN, 2017 - 7 p.
