Search for pair production of excited top quarks in the lepton + jets final state
(Springer-Verlag, 2014-06)
A search is performed for pair-produced spin-3/2 excited top quarks (t[superscript ∗][¯ over t][superscript ∗]), each decaying to a top quark and a gluon. The search uses data collected with the CMS detector from pp ...
Search for physics beyond the standard model in dilepton mass spectra in proton-proton collisions at √s = 8 TeV
(Springer-Verlag, 2015-04)
Dimuon and dielectron mass spectra, obtained from data resulting from proton-proton collisions at 8 TeV and recorded by the CMS experiment, are used to search for both narrow resonances and broad deviations from standard ...
Measurement of J/ψ and ψ(2S) prompt double-differential cross sections in pp collisions at √s = 7 TeV
(American Physical Society, 2015-05)
The double-differential cross sections of promptly produced J/ψ and ψ(2S) mesons are measured in pp collisions at √s = 7 TeV, as a function of transverse momentum p[subscript T] and absolute rapidity |y|. The analysis ...
Constraints on the spin-parity and anomalous HVV couplings of the Higgs boson in proton collisions at 7 and 8 TeV
(American Physical Society, 2015-07)
The study of the spin-parity and tensor structure of the interactions of the recently discovered Higgs boson is performed using the H → ZZ,Zγ[superscript ∗],γ[superscript ∗]γ[superscript ∗] → 4ℓ, H → WW → ℓνℓν, and H → γγ ...
Search for heavy majorana neutrinos in μ[superscript ±]μ[superscript ±] + jets events in proton–proton collisions at √s = 8 TeV
(Elsevier, 2015-07)
A search is performed for heavy Majorana neutrinos (N) using an event signature defined by two muons of the same charge and two jets (μ[superscript ±]μ[superscript ±]jj). The data correspond to an integrated luminosity of ...
Measurement of the cross section ratio σ[subscript t[bar over t]b[bar over b]]/σ[subscript t[bar over t]jj] in pp collisions at √s = 8 TeV
(Elsevier, 2015-04)
The first measurement of the cross section ratio σ[subscript t[bar over t]b[bar over b]/σ[subscript t[bar over t]jj] is presented using a data sample corresponding to an integrated luminosity of 19.6 fb[superscript −1] ...
Search for physics beyond the standard model in final states with a lepton and missing transverse energy in proton-proton collisions at √s = 8 TeV
(American Physical Society, 2015-05)
A search for new physics in proton-proton collisions having final states with an electron or muon and missing transverse energy is presented. The analysis uses data collected in 2012 with the CMS detector, at an LHC ...
Measurement of the Top Quark Pair Production Cross Section in Proton-Proton Collisions at √s = 13 TeV
(American Physical Society, 2016-02)
The top quark pair production cross section is measured for the first time in proton-proton collisions at √s = 13 TeV by the CMS experiment at the CERN LHC, using data corresponding to an integrated luminosity of ...
Measurement of the cross section and angular correlations for associated production of a Z boson with b hadrons in pp collisions at √s = 7 TeV
(Springer-Verlag, 2013-12)
A study of proton-proton collisions in which two b hadrons are produced in association with a Z boson is reported. The collisions were recorded at a centre-of-mass energy of 7 TeVwith the CMS detector at the LHC, for an ...
Measurement of isolated photon production in pp and PbPb collisions at √s[subscript NN] = 2.76 TeV
