This Report summarizes the results of activities in 2012 and first half 2013 LHC Higgs Cross Section Working Group. The main goal working group was to present state art Physics at LHC, integrating all new that have appeared last few years. report follows Handbook Sections: 1. Inclusive Observables (CERN-2011-002) second 2. Differential Distributions (CERN-2012-002). After discovery a boson mid-2012 this focuses on refined prediction Standard Model (SM) phenomenology around experimentally...
The discovery by the ATLAS and CMS experiments of a new boson with mass around 125 GeV measured properties compatible those Standard-Model Higgs boson, coupled absence discoveries phenomena beyond Standard Model at TeV scale, has triggered interest in ideas for future factories. A circular e+e- collider hosted 80 to 100 km tunnel, TLEP, is among most attractive solutions proposed so far. It clean experimental environment, produces high luminosity top-quark, W Z studies, accommodates multiple...
The observation of Higgs boson production in association with a top quark-antiquark pair is reported, based on combined analysis proton-proton collision data at center-of-mass energies √s = 7, 8, and 13 TeV, corresponding to integrated luminosities up 5.1, 19.7, 35.9 fb^(-1), respectively. were collected the CMS detector CERN LHC. results statistically independent searches for bosons produced conjunction decaying pairs W bosons, Z photons, τ leptons, or bottom quark jets are maximize...
For an efficient data taking, the Electromagnetic Calorimeter of CMS experiment must be limited to 10% full event size (1MB). Other requirements limit average 2kB per acquisition link. These conditions imply a reduction factor close twenty on collected. The filtering in readout detector is discussed. Test beam are used study digital applied channels and simulation allows estimate energy thresholds achieve desired suppression factor.
The long-term stability of Resistive Plate Chambers (RPCs) with glass electrodes was studied for one year a dedicated test station hosting about 10 m2 detectors. RPCs were operated in streamer mode ternary gas mixture containing argon (27%), isobutane (9%) and tetrafluoroethane (64%). Environmental conditions kept under control and, particular, the water pollution gas, deemed responsible degradation RPC performance, monitored never to exceed 30 ppm exhaust line. Evidence substantial aging...
For an efficient data taking, the electromagnetic calorimeter (ECAL) of CMS experiment must be limited to 10% full event size (1 MB). Other requirements limit average 2 kB per acquisition link. These conditions imply a reduction factor close twenty on collected. The filtering in readout ECAL detector is discussed.

In this paper we give a description of the database services for control and monitoring electromagnetic calorimeter CMS experiment at LHC. After general software infrastructure, present organization tables in database, that has been designed order to simplify development interfaces. This feature is achieved including each relevant table. We also some estimation about final size performance system.
The electromagnetic calorimeter of the CMS experiment at CERN is an homogeneous made about 80000 Lead Tungstate crystals, that will start to operate LHC end 2007. From June November 2006, ten barrel Supermodules (1700 crystals each) were exposed beam SPS, both in standalone and association with portions Hadron Calorimeter. We present description system used configure readout during campaign. full set final electronics boards was employed, together pre-series version data acquisition...
The Level-1 Trigger plays a major role in the CMS experiment allowing reduction of raw event rate at Large Hadron Collider. Its decision is based on information from electromagnetic and hadronic calorimeters as well muon detectors. electronics calorimeter generate deliver basic quantities called “Trigger Primitives” which correspond to local energy deposits created by showers. In order ensure correct generation trigger primitives electronics, special software an emulator has been...
On behalf of the CMS CollaborationThe measurement inclusive photon production is a crucial step for understanding Standard Model Physics at Large Hadron Collider (LHC) and an important prerequisite many new physics searches.The identification photons' experimental signatures their discrimination against instrumental background due to hadronic activity challenging task in severe LHC environment.A robust set selection criteria isolated photons start-up using detector was developed.In this...
The CMS detector at LHC is equipped with a high precision lead tungstate crystal electromagnetic calorimeter (ECAL). front-end boards and the photodetectors are monitored using network of DCU (Detector Control Unit) chips located on electronics. data accessible through token rings controlled by an XDAQ-based software component. Relevant parameters transferred to DCS System) stored into Condition DataBase. operational experience from ECAL commissioning experimental cavern discussed summarized.
