Mechanical stability of the CMS strip tracker measured with a laser alignment system
(Journal of Instrumentation, 2017)
The CMS tracker consists of 206m(2) of silicon strip sensors assembled on carbon fibre composite structures and is designed for operation in the temperature range from -25 to + 25 degrees C. The mechanical stability of ...
The CMS trigger system
(Journal of Instrumentation, 2017)
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 interest from a GHz (MHz) interaction rate ...
Particle-flow reconstruction and global event description with the CMS detector
(Journal of Instrumentation, 2017)
The CMS apparatus was identified, a few years before the start of the LHC operation at CERN, to feature properties well suited to particle-flow (PF) reconstruction: a highly-segmented tracker, a fine-grained electromagnetic ...
Intercalibration of the barrel electromagnetic calorimeter of the CMS experiment at start-up
(Journal of Instrumentation, 2008)
Calibration of the relative response of the individual channels of the barrel electromagnetic calorimeter of the CMS detector was accomplished, before installation, with cosmic ray muons and test beams. One fourth of the ...
Jet energy scale and resolution in the CMS experiment in pp collisions at 8 TeV
(Journal of Instrumentation, 2017)
Improved jet energy scale corrections, based on a data sample corresponding to an integrated luminosity of 19.7 fb(-1) collected by the CMS experiment in proton-proton collisions at a center-of-mass energy of 8 TeV, are ...
