 Construction and first beam-tests of silicon-tungsten prototype modules for the CMS High Granularity Calorimeter for HL-LHC / Romeo, Francesco (Beijing, Inst. High Energy Phys.) /CMS Collaboration The High Granularity Calorimeter (HGCAL) is the technology choice of the CMS collaboration for the endcap calorimetry upgrade planned to cope with the harsh radiation and pileup environment at the High Luminosity-LHC. The HGCAL is realized as a sampling calorimeter, including an electromagnetic compartment comprising 28 layers of silicon pad detectors with pad areas of 0.5 - 1.0 square centimetres interspersed with absorbers.

 Commissioning and integration testing of the DAQ system for the CMS GEM upgrade / Castaneda Hernandez, Alfredo Martin (Texas A-M) /CMS Collaboration The CMS muon system will undergo a series of upgrades in the coming years to preserve and extend its muon detection capabilities during the High Luminosity LHC.The first of these will be the installation of triple-foil GEM detectors in the CMS forward region with the goal of maintaining trigger rates and preserving good muon reconstruction, even in the expected harsh environment.In 2017 the CMS GEM project is looking to achieve a major milestone in the project with the installation of 5 super-chambers in CMS; this exercise will allow for the study of services installation and commissioning, and integration with the rest of the subsystems for the first time. An overview of the DAQ system will be given with emphasis on the usage during chamber quality control testing, commissioning in CMS, and integration with the central CMS system..

 Operational Experience with Radioactive Source Calibration of the CMS Hadron Endcap Calorimeter Wedges with Phase I Upgrade Electronics / Bilki, Burak (Iowa U.) /CMS Collaboration The Phase I Upgrade of the CMS Hadron Endcap Calorimeters consist of new photodetectors (Silicon Photomultipliers in place of Hybrid Photo-Diodes) and front-end electronics (QIE11). The upgrade will allow the elimination of the high amplitude noise and drifting response of the Hybrid Photo-Diodes, at the same time enabling the mitigation of the radiation damage of the scintillators and the wavelength shifting fibers with a larger spectral acceptance of the Silicon Photomultipliers.

 Commissioning of the CMS Hadron Forward Calorimeters Phase I Upgrade / Bilki, Burak (Iowa U.) /CMS Collaboration The final phase of the CMS Hadron Forward Calorimeters Phase I upgrade is being performed during the Extended Year End Technical Stop of 2016 â?? 2017. In the framework of the upgrade, the PMT boxes are being reworked to implement two channel readout in order to exploit the benefits of the multi-anode PMTs in background tagging and signal recovery.

 Searches for dark matter at CMS in events with missing transverse energy / Laner Ogilvy, Christian (Imperial Coll., London) /CMS Collaboration Many theories predict candidates to the dark matter particles that are light enough to be produced at the LHC. This talk presents the searches for dark matter at CMS in events with missing transverse energy, focusing on the recent results obtained using data collected in 2016..

 Dark matter search in CMS / Vartak, Adish (UC, San Diego) /CMS Collaboration The dark matter search program at the LHC covers a wide range of final states and targets a variety of possible interactions between dark matter and standard model particles. A summary of the dark matter searches performed at the CMS experiment, using proton-proton collision data collected at a center of energy of 13 TeV, is presented.Searches performed in various final states are described, and results interpreted in terms of several dark matter models are presented.

 FPGA-based Real-time Charged Particle Trajectory Reconstruction at the Large Hadron Collider / Bartz, Edward Hugo (Rutgers U., Piscataway) ; Chaves, Jorge Enrique (Cornell U.) ; Gershtein, Yury (Rutgers U., Piscataway) ; Halkiadakis, Eva (Rutgers U., Piscataway) ; Hildreth, Michael (Notre Dame U.) ; Kyriacou, Savvas (Rutgers U., Piscataway) ; Lannon, Kevin Patrick (Notre Dame U.) ; Lefeld, Anthony James (Ohio State U.) ; Ryd, Anders Per Erik (Cornell U.) ; Skinnari, Louise (Cornell U.) et al. The upgrades of the Compact Muon Solenoid particle physics experiment at CERN's Large Hadron Collider provide a major challenge for the real-time collision data selection. This paper presents a novel approach to pattern recognition and charged particle trajectory reconstruction using an all-FPGA solution. [...] CMS-CR-2017-100.- Geneva : CERN, 2017 - 9 p.

 Search for new resonances decaying into W, Z and H bosons at CMS / Zucchetta, Alberto (Zurich U.) /CMS Collaboration Beyond the standard model theories like Extra-Dimensions and Composite Higgs scenarios predict the existence of very heavy resonances compatible with a spin 0 (Radion), spin 1 (W', Z') and spin 2 (Graviton) particle with large branching fractions in pairs of standard model bosons and negligible branching fractions to light fermions. We present an overview of searches for new physics containing W, Z or H bosons in the final state, using proton-proton collision data collected with the CMS detector at the CERN LHC.
