Performance of heavy-flavour jet identification in Lorentz-boosted topologies in proton-proton collisions at = 13 TeV
CMS Collaboration
Measurements in the highly Lorentz-boosted regime provoke increased interest in probing the Higgs boson properties and in searching for particles beyond the standard model at the L…
Operation and performance of the CMS silicon strip tracker with proton-proton collisions at the CERN LHC
CMS Collaboration
Salient aspects of the commissioning, calibration, and performance of the CMS silicon strip tracker are discussed, drawing on experience during operation with proton-proton collisi…
The CMS Barrel Timing Layer: test beam confirmation of module timing performance
F. Addesa, P. Akrap, A. Albert +127
First of its kind, the barrel section of the MIP Timing Detector is a large area timing detector based on LYSO:Ce crystals and SiPMs which are required to operate in an unprecedent…
Performance of the CMS high-level trigger during LHC Run 2
CMS Collaboration
The CERN LHC provided proton and heavy ion collisions during its Run 2 operation period from 2015 to 2018. Proton-proton collisions reached a peak instantaneous luminosity of 2.1 $…
Optimization of LYSO crystals and SiPM parameters for the CMS MIP timing detector
F. Addesa, T. Anderson, P. Barria +68
For the High-Luminosity (HL-LHC) phase, the upgrade of the Compact Muon Solenoid (CMS) experiment at CERN will include a novel MIP Timing Detector (MTD). The central part of MTD, t…
Performance of the CMS electromagnetic calorimeter in pp collisions at = 13 TeV
CMS Collaboration
The operation and performance of the Compact Muon Solenoid (CMS) electromagnetic calorimeter (ECAL) are presented, based on data collected in pp collisions at = 13 TeV a…
Portable acceleration of CMS computing workflows with coprocessors as a service
CMS Collaboration
Computing demands for large scientific experiments, such as the CMS experiment at the CERN LHC, will increase dramatically in the next decades. To complement the future performance…
Reconstruction of signal amplitudes in the CMS electromagnetic calorimeter in the presence of overlapping proton-proton interactions
CMS Collaboration
A template fitting technique for reconstructing the amplitude of signals produced by the lead tungstate crystals of the CMS electromagnetic calorimeter is described. This novel app…
The CMS trigger system
CMS Collaboration
This paper describes the CMS trigger system and its performance during Run 1 of the LHC. The trigger system consists of two levels designed to select events of potential physics in…
