Alignment of the CMS tracker with LHC and cosmic ray data
(IOP Publishing, 2014-06)
Results are reported from a search for supersymmetry in pp collisions at a center-of-mass energy of 8 TeV, based on events with a single isolated lepton (electron or muon) and multiple jets, at least two of which are ...
Constraints on the Higgs boson width from off-shell production and decay to Z-boson pairs
Constraints are presented on the total width of the recently discovered Higgs boson, Gamma(H), using its relative on-shell and off-shell production and decay rates to a pair of Z bosons, where one Z boson decays to an ...
Description and performance of track and primary-vertex reconstruction with the CMS tracker
(IOP Publishing, 2014-10)
A description is provided of the software algorithms developed for the CMS tracker both for reconstructing charged-particle trajectories in proton-proton interactions and for using the resulting tracks to estimate the ...
Determination of the top-quark pole mass and strong coupling constant from the tt production cross section in pp collisions at root s=7 TeV
The inclusive cross section for top-quark pair production measured by the CMS experiment in proton–proton collisions at a center-of-mass energy of 7 TeV is compared to the QCD prediction at next-to-next-to-leading order ...
Measurement of associated W plus charm production in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2014-02)
Measurements are presented of the associated production of a W boson and a charm-quark jet (W + c) in pp collisions at a center-of-mass energy of 7 TeV. The analysis is conducted with a data sample corresponding to a total ...
Evidence for the 125 GeV Higgs boson decaying to a pair of tau leptons
(Springer Science+Business Media, 2014-05)
A search for a standard model Higgs boson decaying into a pair of tau leptons is performed using events recorded by the CMS experiment at the LHC in 2011 and 2012. The dataset corresponds to an integrated luminosity of 4.9 ...
Evidence of b-Jet quenching in PbPb collisions at root S-NN=2.76 TeV
(American Physical Society, 2014-09-26)
The production of jets associated to bottom quarks is measured for the first time in PbPb collisions at a center-of-mass energy of 2.76 TeV per nucleon pair. Jet spectra are reported in the transverse momentum (pT) range ...
Measurement of four-jet production in proton-proton collisions at root s=7 TeV
(American Physical Society, 2014-05-01)
Measurements of the differential cross sections for the production of exactly four jets in proton-proton collisions are presented as a function of the transverse momentum p(T) and pseudorapidity eta, together with the ...
