Combined search for anomalous pseudoscalar HW couplings in VH(H -> b(b)over-bar) production and H -> VV decay
(Elsevier, 2016)
A search for anomalous pseudoscalar couplings of the Higgs boson H to electroweak vector bosons V (= W or Z) in a sample of proton-proton collision events corresponding to an integrated luminosity of 18.9 fb(-1) at a ...
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 ...
Measurement of the Higgs boson production rate in association with top quarks in final states with electrons, muons, and hadronically decaying tau leptons at ?s=13Te
(Springer Science and Business Media Deutschland GmbH, 2021)
The rate for Higgs (H) bosons production in association with either one (t H) or two (t t ¯ H) top quarks is measured in final states containing multiple electrons, muons, or tau leptons decaying to hadrons and a neutrino, ...
Measurement of differential t t ¯ production cross sections using top quarks at large transverse momenta in pp collisions at s =13 TeV MEASUREMENT of DIFFERENTIAL t t ¯ ... SIRUNYAN A. M. et al.
(American Physical Society, 2021)
A measurement is reported of differential top quark pair (tt¯) production cross sections, where top quarks are produced at large transverse momenta. The data collected with the CMS detector at the LHC are from pp collisions ...
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 t(t)over-bar normalised multi-differential cross sections in pp collisions at root s=13 TeV, and simultaneous determination of the strong coupling strength, top quark pole mass, and parton distribution functions
(Springer, 2020)
Normalised multi-differential cross sections for top quark pair (t (t) over bar) production are measured in proton-proton collisions at a centre-of-mass energy of 13 TeV using events containing two oppositely charged ...
Measurement of inclusive jet cross sections in pp and PbPb collisions at root s(NN)=2.76 TeV
(Amer Physical Soc, 2017)
Inclusive jet spectra from pp and PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76 TeV, collected with the CMS detector at the CERN Large Hadron Collider, are presented. Jets are reconstructed with three ...
Comparing transverse momentum balance of b jet pairs in pp and PbPb collisions at root s(NN)=5.02 TeV
(Springer, 2018)
The transverse momentum balance of pairs of back-to-back b quark jets in PbPb and pp collisions recorded with the CMS detector at the LHC is reported. The center-of-mass energy in both collision systems is 5.02 TeV per ...
