Suppression of Excited gamma States Relative to the Ground State in Pb-Pb Collisions at root s(NN)=5.02 TeV
(Amer Physical Soc, 2018)
The relative yields of gamma mesons produced in pp and Pb-Pb collisions at root s(NN) = 5.02 TeV and reconstructed via the dimuon decay channel are measured using data collected by the CMS experiment. Double ratios are ...
Study of Z Boson Production in PbPb Collisions at root s(NN)=2.76 TeV
(Amer Physical Soc, 2011)
A search for Z bosons in the mu(+)mu(-) decay channel has been performed in PbPb collisions at root s(NN) = 2.76 TeV with the CMS detector at the LHC, in a 7.2 mu b(-1) data sample. The number of opposite-sign muon pairs ...
Study of the underlying event at forward rapidity in pp collisions at root s=0.9, 2.76, and 7 TeV
The underlying event activity in proton-proton collisions at forward pseudorapidity (-6.6 < eta < -5.2) is studied with the CMS detector at the LHC, using a novel observable: the ratio of the forward energy density, ...
Suppression of non-prompt J/psi, prompt J/psi, and Upsilon(1S) in PbPb collisions at root s(NN)=2.76 TeV
Yields of prompt and non-prompt J/psi ,as well as Upsilon(1S) mesons, are measured by the CMS experiment via their mu(+)mu(-) decays in PbPb and pp collisions at root s(NN) - 2.76TeV for quarkonium rapidity |y| < 2.4. ...
Tests of CMS hadron forward calorimeter upgrade readout box prototype
(Iop Publishing Ltd, 2012)
A readout box prototype for the CMS Hadron Forward calorimeter upgrade was built and tested in the CERN H2 beamline. The prototype was designed to enable simultaneous tests of different readout options for the four anode ...
Study of Z boson production in pPb collisions at root S-NN=5.02 TeV
The production of Z bosons in pPb collisions at root S-NN = 5.02 TeV is studied by the CMS experiment via the electron and muon decay channels. The inclusive cross section is compared to pp collision predictions, and found ...
