Limits on the Higgs boson lifetime and width from its decay to four charged leptons
(American Physical Society, 2015-10)
Constraints on the lifetime and width of the Higgs boson are obtained from H → ZZ → 4ℓ events using data recorded by the CMS experiment during the LHC run 1 with an integrated luminosity of 5.1 and 19.7 fb[superscript −1] ...
Comparison of the Z/γ[superscript ∗] + jets to γ + jets cross sections in pp collisions at √s = 8 TeV
(Springer Nature, 2015-10)
A comparison of the differential cross sections for the processes Z/γ[superscript *] + jets and photon (γ)+jets is presented. The measurements are based on data collected with the CMS detector at √s=8 TeV. corresponding ...
Measurement of the Z boson differential cross section in transverse momentum and rapidity in proton–proton collisions at 8 TeV
(Elsevier BV, 2015-07)
We present a measurement of the Z boson differential cross section in rapidity and transverse momentum using a data sample of pp collision events at a centre-of-mass energy √s = 8 TeV, corresponding to an integrated ...
Search for pair-produced resonances decaying to jet pairs in proton–proton collisions at √s = 8 TeV
(Elsevier, 2015-04)
Results are reported of a general search for pair production of heavy resonances decaying to pairs of hadronic jets in events with at least four jets. The study is based on up to 19.4 fb[superscript −1] of integrated ...
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 ...
