 Higgs boson production in association with top quarks in CMS / Caminada, Lea Michaela (Zurich U.) /CMS Collaboration In this talk searches for Higgs bosons produced in association with top quarks are presented. The searches are performed using the data collected during the first LHC run at a center-of-mass energy of 7 and 8 TeV and results are presented for different Higgs boson decay final states, including bbbar, tautau, WW*/ZZ* and gg, as well as their combination.

 Higgs boson properties and tests of the Standard Model at CMS / Brandstetter, Johannes (Vienna, OAW) /CMS Collaboration The measurements of the Higgs boson properties, mass, spin/CP, couplings, off-shell cross sections and constraints on invisible width, as well as other Standard model measurements at CMS will be presented. The analysis is based on pp collision data collected at centre-of-mass energies of 7 and 8 TeV by the CMS experiment at the LHC, corresponding to integrated luminosities of 5/fb and 20/fb, respectively..

 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.

 CMS inner detector: the Run 1 to Run 2 transition, and first experience of Run 2 / Lange, Clemens (Zurich U.) /CMS Collaboration The CMS inner detector is the largest silicon tracker ever built. Located around the center of CMS where the LHC particle beams are brought into collision, it consists of a hybrid pixel detector with 66 million channels and a 200~m$^2$ silicon strip detector with about 10~million readout channels.
