Search for a Narrow Resonance Lighter than 200 GeV Decaying to a Pair of Muons in Proton-Proton Collisions at root s=13 TeV
(Amer Physical Soc, 2020)
A search is presented for a narrow resonance decaying to a pair of oppositely charged muons using root s = 13 TeV proton-proton collision data recorded at the LHC. In the 45-75 and 110-200 GeV resonance mass ranges, the ...
Dose rate effects in the radiation damage of the plastic scintillators of the CMS hadron endcap calorimeter
(Iop Publishing Ltd, 2016)
We present measurements of the reduction of light output by plastic scintillators irradiated in the CMS detector during the 8 TeV run of the Large Hadron Collider and show that they indicate a strong dose rate effect. The ...
Radioactive source calibration test of the CMS Hadron Endcap Calorimeter test wedge with Phase I upgrade electronics
(Iop Publishing Ltd, 2017)
The Phase I upgrade of the CMS Hadron Endcap Calorimeters consists of new photodetectors (Silicon Photomultipliers in place of Hybrid Photo-Diodes) and front-end electronics. The upgrade will eliminate the noise and the ...
Brightness and uniformity measurements of plastic scintillator tiles at the CERN H2 test beam
(Iop Publishing Ltd, 2018)
We study the light output, light collection efficiency and signal timing of a variety of organic scintillators that are being considered for the upgrade of the hadronic calorimeter of the CMS detector. The experimental ...
Performance of the reconstruction and identification of high-momentum muons in proton-proton collisions at root s=13 TeV
(Iop Publishing Ltd, 2020)
The CMS detector at the LHC has recorded events from proton-proton collisions, with muon momenta reaching up to 1.8 TeV in the collected dimuon samples. These high-momentum muons allow direct access to new regimes in physics ...
Measurement of prompt and nonprompt charmonium suppression in PbPb collisions at 5.02 TeV
(Institute for Ionics, 2018)
The nuclear modification factors of J/psi and psi(2S) mesons are measured in PbPb collisions at a centre-of-mass energy per nucleon pair of root S-NN = 5.02 TeV. The analysis is based on PbPb and pp data samples collected ...
The very forward CASTOR calorimeter of the CMS experiment
(Iop Publishing Ltd, 2021)
The physics motivation, detector design, triggers, calibration, alignment, simulation, and overall performance of the very forward CASTOR calorimeter of the CMS experiment are reviewed. The CASTOR Cherenkov sampling ...
Measurements of production cross sections of WZ and same-sign WW boson pairs in association with two jets in proton-proton collisions at root s=13 TeV
(Elsevier, 2020)
Measurements of production cross sections of WZ and same-sign WW boson pairs in association with two jets in proton-proton collisions at root s = 13 TeV at the LHC are reported. The data sample corresponds to an integrated ...
Measurements of production cross sections of polarized same-sign W boson pairs in association with two jets in proton-proton collisions at root s=13 TeV
(Elsevier, 2021)
The first measurements of production cross sections of polarized same-sign (WW +/-)-W-+/- boson pairs in proton-proton collisions are reported. The measurements are based on a data sample collected with the CMS detector ...
Evidence for electroweak production of four charged leptons and two jets in proton-proton collisions at root s=13 TeV
(Elsevier, 2021)
Evidence is presented for the electroweak (EW) production of two jets (jj) in association with two Z-bosons and constraints on anomalous quartic gauge couplings are set. The analysis is based on a data sample of proton-proton ...
