 CMS Software and Computing Ready for Run 2 / Bloom, Kenneth Arthur (Nebraska U.) /CMS Collaboration In Run 1 of the Large Hadron Collider, software and computing was a strategic strength of the Compact Muon Solenoid experiment. The timely processing of data and simulation samples and the excellent performance of the reconstruction algorithms played an important role in the preparation of the full suite of searches used for the observation of the Higgs boson in 2012.

 Latest results on anomalous gauge couplings from CMS / Avdeeva, Ekaterina (Nebraska U.) /CMS Collaboration The paper presents results from CMS for limits on anomalous triple and quartic gauge couplings using data collected at the LHC at center-of-mass energies 7 and 8 TeV and corresponding integrated luminosities of 5 fb$^{-1}$ and 19.5 fb$^{-1}$ respectively. All results are consistent with the Standard Model predictions.. CMS-CR-2015-217.- Geneva : CERN, 2015 - 12 p. Fulltext: PDF; In : PHOTON 2015, Novosibirsk, Russia, 15 - 19 Jun 2015

 Search for Standard Model Production of Four Top Quarks / Heilman, Jesse (UC, Riverside) /CMS Collaboration A search is presented for standard model (SM) production of four top quarks in pp collisions at the LHC. Using Run-1 data corresponding to an integrated luminosity of 19 fb$^{-1}$, a combination of kinematic reconstruction and multivariate techniques is used to distinguish between the small signal ($\approx 1$ fb) and backgrounds in the lepton + jets channel.

 Latest results on Higgs final-states with photons in CMS / Tao, Junquan (Beijing, Inst. High Energy Phys.) /CMS Collaboration The analyses and results of standard model predicted Higgs boson with photons in the final states, using the dataset collected by the CMS experiment in proton-proton collisions during the LHC running periods in years 2011 and 2012, are reviewed. Observation of the diphoton decay mode of the recently discovered Higgs boson ($H \rightarrow \gamma\gamma$) with a local significance of 5.7 $\sigma$ and measurement of some of its properties are presented firstly.

 Vector Boson Scattering prospects for High-Luminosity LHC at CMS in the same sign WW final state / Gerosa, Raffaele Angelo (INFN, Milan Bicocca ; Milan Bicocca U.) /CMS Collaboration A feasibility study is presented for Vector Boson Scattering measurements in the same-sign WW final state, that can be performed during the high luminosity phase of the LHC. Particular emphasis is given to the expected performances of the detector in different upgrade scenarios, which are compared to each other and to the results attained with the current, aged technology..

 Search for a Higgs boson decaying to a pair of Higgs bosons (hh or hA) or for a Higgs boson decaying to Zh/ZA at CMS / Lane, Rebecca (Imperial Coll., London) /CMS Collaboration Searches for Higgs bosons decaying to a pair of Higgs bosons (hh or hA) or for a Higgs boson decaying to Zh/ZA are presented. Different analyses involving Higgs boson decays into bottom-quarks, tau pairs, and diphotons will be summarized in this talk.. CMS-CR-2015-216.- Geneva : CERN, 2015 - 8 p.
