The CMS electromagnetic calorimeter

From 2007 the new CERN proton proton collider will start collisions that could open new perspectives in the fields of high energy particle physics. The CMS experiment at the LHC is in advanced construction phase. In particular new physics could be discovered thanks to the CMS precise electromagnetic calorimeter (ECAL) made of about 75000 scintillating PbWO 4 crystals. A description of the ECAL ...

CMS Central Hadron Calorimeter

We present a description of the CMS central hadron calorimeter. We describe the production of the 1996 CMS hadron testbeam module. We show the results of the quality control tests of the testbeam module. We present some results of the 1995 CMS hadron testbeam. The design of the CMS detector starts with the 4 T solenoidal magnet of length 13 m and inner diameter 5.9 m. The magnet determines many...

Online Selection of π(η) → γγ decays and the Potential for Intercalibrating the CMS Barrel Electromagnetic Calorimeter

Precise in situ calibration of the CMS electromagnetic calorimeter (ECAL) will be of crucial importance to fully exploit the physics reach of the CMS detector. In particular a precise calibration is needed to fully benefit from the excellent energy resolution of the calorimeter, approaching 0.5% for high energy unconverted photons. The resolution for photons is particularly important for the di...

Measurement of Jets with the CMS Detector at the LHC

The jet reconstruction algorithms and calibration techniques implemented in the CMS reconstruction software are studied with high-statistics Monte Carlo samples of QCD dijet events. Generated events are passed through a full detector-level simulation of the CMS detector including readout digitization in the presence of pile-up at an instantaneous luminosity of L = 2× 10 cms. Effects of detector...

Performance of electron reconstruction and selection with the CMS detector in proton-proton collisions at sqrt(s)=8 TeV

The performance and strategies used in electron reconstruction and selection at CMS are presented based on data corresponding to an integrated luminosity of 19.7 fb−1, collected in proton-proton collisions at √ s = 8 TeV at the CERN LHC. The paper focuses on prompt isolated electrons with transverse momenta ranging from about 5 to a few 100 GeV. A detailed description is given of the algorithms...
