 Capacitively coupled hybrid pixel assemblies for the CLIC vertex detector / Alipour Tehrani, Niloufar (Eidgenoessische Tech. Hochschule Zuerich (CH)) ; Arfaoui, Samir ; Mayoraz, Benoit (CERN) ; Dannheim, Dominik (CERN) ; Dette, Karola (Technische Universitaet Dortmund (DE)) ; Hynds, Daniel (CERN) ; Kulis, Szymon (CERN) ; Peric, Ivan (KIT - Karlsruhe Institute of Technology (DE)) ; Petric, Marko (CERN) ; Redford, Sophie (CERN) et al. The vertex detector at the proposed CLIC multi-TeV linear e+e- collider must have minimal material content and high spatial resolution, combined with accurate time-stamping to cope with the expected high rate of beam-induced backgrounds. One of the options being considered is the use of active sensors implemented in a commercial high-voltage CMOS process, capacitively coupled to hybrid pixel ASICs.

 CMS Forward and Small-x QCD Physics Results / Grebenyuk, Anastasia (Brussels U.) /CMS Collaboration An overview of the forward and small-x QCD physics programme at CMS is given. It covers the measurement of the leading charged particle and leading jet cross sections, soft diffractive cross section, dijet production with a large rapidity gap, exclusive WW production and constraints on Anomalous Quartic Gauge Couplings.

 Jet production and $\alpha_{s}$ measurements at CMS / Flouris, Giannis (Ioannina U.) /CMS Collaboration The measurements of inclusive jet, dijet and trijet cross sections, of the dijet azimuthal decorrelations, the ratio of the inclusive 3-jet to 2-jet cross sections are presented. The measurements use the samples of proton-proton collisions collected with the CMS detector at the LHC at a center-of-mass energy of 7 and 8 TeV.. CMS-CR-2015-149.- Geneva : CERN, 2015 - 6 p.

 CMS Developments for Track-Triggers / De Mattia, Marco (Texas A-M) /CMS Collaboration The High Luminosity LHC (HL-LHC) is expected to deliver luminosities of 5$\times10^{34}$cm$^{-2}$s$^{-1}$, with an average of about 140 overlapping proton-proton collisions per bunch crossing. These extreme pileup conditions place stringent requirements on the trigger system to be able to cope with the resulting event rates. [...] CMS-CR-2015-154.- Geneva : CERN, 2015 - 11 p.

 CMS results on electroweak probes from LHC Run1 / Zsigmond, Anna Julia (Budapest, RMKI) /CMS Collaboration Electroweak boson production is an important benchmark process in high-energy heavy-ion collisions at the LHC. The Z and W~bosons do not participate in the strong interaction and their leptonic decays provide medium-blind probes of the initial state of the collisions.

 Measurements of the top quark properties in $t\bar{t}$ production using the CMS detector at the LHC / Roscher, Frank Sebastian (Karlsruhe U., EKP) /CMS Collaboration Several recent CMS measurements of properties in top quark pair production are presented. This encompasses 8 TeV measurements of the $\mathrm{t\bar{t}+W}$, $\mathrm{t\bar{t}+Z}$, and $\mathrm{t\bar{t}+\gamma}$ production cross sections, two different measurements of the charge asymmetry at 8 TeV, a 7 TeV measurement of the top quark polarization, and measurements of the top quark spin correlation in the dilepton channel at 7 TeV as well as in the muon+jets channel at 8 TeV..

 Upgrades of the CMS pixel detector for the HL-LHC / Stringer, Robert Wayne (Kansas U.) /CMS Collaboration In 2023, the LHC will be upgraded to the HL-LHC, increasing the luminosity to 5 x 10\textsuperscript{34} cm\textsuperscript{-2}~s\textsuperscript{-1}. The increased luminosity will present new challenges, such as higher data rates and increased radiation. [...] CMS-CR-2015-159.- Geneva : CERN, 2015 - 7 p.
