 Search for the Standard Model Higgs Boson at CMS / Mohammadi, Abdollah (Brussels U.) /CMS Collaboration A search has been performed for the Standard Model (SM) Higgs boson in different production modes and decay channels. The results are based on up to 5 fb$^{-1}$ of 7 TeV and up to 20 fb$^{-1}$ of 8 TeV proton-proton collisions data accumulated by the CMS experiment at LHC in 2011 and 2012.

 STATUS REPORT ON THE CMS FORWARD MUON UPGRADE WITH LARGE-SIZE TRIPLE-GEM DETECTORS / Barria, Patrizia (Brussels U.) /CMS Collaboration For the LHC High Luminosity phase (HL-LHC) the CMS GEM Collaboration is planning to install new large size (990 x 440-220 mm2) triple-GEM detectors, equipped with a new readout system, in the forward region of the muon system (1.5 lt IÎ·I lt 2.2) of the CMS detector. Combining triggering and tracking functionalities the new triple-Gas Electron Multiplier (GEM) chambers will not only improve the performance of the CMS muon trigger, but will also improve the muon identification and track reconstruction.

 The CMS pixel readout chip for the Phase 1 Upgrade / Hits, Dmitry (Zurich, ETH) ; Starodumov, Andrey (Zurich, ETH) /CMS Collaboration The present CMS pixel Read Out Chip (ROC) was designed for operation at a bunch spacing of 25\,ns and to be efficient up to the nominal instantaneous luminosity of 10$^{34} \rm cm^{-2} \rm s^{-1}$. Based on the excellent LHC performance to date and the upgrade plans for the accelerators, it is anticipated that the instantaneous luminosity could reach $2\times10^{34} \rm cm^{-2} \rm s^{-1}$ before the Long Shutdown 2 (LS2) in 2018, and well above this by the LS3 in 2022.

 CMS pixel detector phase-1 upgrade / Erdmann, Wolfram (PSI, Villigen) /CMS Collaboration The CMS experiment is going to upgrade its pixel detector during Run 2 of the Large Hadron Collider. The new detector will provide an additional tracking layer and increased rate capability, suitable for the projected instantaneous luminosities of Run 2, well beyond the original design targets of the present pixel detector..

 The CMS electromagnetic calorimeter barrel upgrade for High-Luminosity LHC / Obertino, Margherita Maria (INFN, Turin ; Piemonte Orientale U., Novara) /CMS Collaboration The High Luminosity LHC (HL-LHC) will provide unprecedented instantaneous and integrated luminosity. The lead tungstate crystals forming the barrel part of the CMS Electromagnetic Calorimeter (ECAL) will still perform well, even after the expected 3000fb-1 at the end of HL-LHC.

 Exotics/Susy / Knutzen, Simon (Aachen, Tech. Hochsch.) /ATLAS, CMS and LHCB Collaborations The tau lepton is the heaviest of the known charged leptons and therefore provides a unique tool to search for new physics since many new physics models couple more strongly to the third generation. In this paper, recent results from LHC on searches for new physics in the context of SUSY and Exotic decays involving the tau lepton will be presented.. CMS-CR-2014-342.- Geneva : CERN, 2014 - 5 p.

 CMS computing upgrade and evolution / Hernandez Calama, Jose (Madrid, CIEMAT) /CMS Collaboration The distributed Grid computing infrastructure has been instrumental in the successful exploitation of the LHC data leading to the discovery of the Higgs boson. The computing system will need to face new challenges from 2015 on when LHC restarts with an anticipated higher detector output rate and event complexity, but with only a limited increase in the computing resources.

 Challenging Data Management in CMS Computing with Network-aware Systems / Bonacorsi, Daniele (INFN, Bologna ; Bologna U.) ; Wildish, Anthony (Princeton U.) /CMS Collaboration After a successful first run at the LHC, and during the Long Shutdown (LS1) of the accelerator, the workload and data management sectors of the CMS Computing Model are entering into an operational review phase in order to concretely assess area of possible improvements and paths to exploit new promising technology trends. In particular, since the preparation activities for the LHC start, the Networks have constantly been of paramount importance for the execution of CMS workflows, exceeding the original expectations - as from the MONARC model - in terms of performance, stability and reliability.
