Measurement of the W boson helicity in events with a single reconstructed top quark in pp collisions at √s = 8 TeV
(Springer-Verlag, 2015-01)
A measurement of the W boson helicity is presented, where the W boson originates from the decay of a top quark produced in pp collisions. The event selection, optimized for reconstructing a single top quark in the final ...
Search for vector-like T quarks decaying to top quarks and Higgs bosons in the all-hadronic channel using jet substructure
(Springer-Verlag, 2015-06)
A search is performed for a vector-like heavy T quark that is produced in pairs and that decays to a top quark and a Higgs boson. The data analysed correspond to an integrated luminosity of 19.7 fb[superscript −1] collected ...
Study of Vector Boson Scattering and Search for New Physics in Events with Two Same-Sign Leptons and Two Jets
(American Physical Society, 2015-02)
A study of vector boson scattering in pp collisions at a center-of-mass energy of 8 TeV is presented. The data sample corresponds to an integrated luminosity of 19.4 fb[superscript −1] collected with the CMS detector. ...
Search for long-lived particles that decay into final states containing two electrons or two muons in proton-proton collisions at √s = 8 TeV
(American Physical Society, 2015-03)
A search is performed for long-lived particles that decay into final states that include a pair of electrons or a pair of muons. The experimental signature is a distinctive topology consisting of a pair of charged leptons ...
Search for flavor changing neutral currents in top quark decays in pp collisions at 7 TeV
(Elsevier, 2012-12)
The results of a search for flavor changing neutral currents in top quark decays t→Zq in events with a topology compatible with the decay chain tt¯→Wb+Zq→ℓνb+ℓℓq are presented. The search is performed with a data sample ...
Measurement of the t[bar over t] production cross section in pp collisions at √s = 8 TeV in dilepton final states containing one τ lepton
(Elsevier, 2014-10)
The top-quark pair production cross section is measured in final states with one electron or muon and one hadronically decaying τ lepton from the process t[bar over t] → (ℓν[subscript ℓ])(τν[subscript τ])b[bar over b], ...
Search for a Narrow, Spin-2 Resonance Decaying to a Pair of Z Bosons in the q[bar over q]ℓ[superscript +]ℓ[superscript −] Final State
(Elsevier, 2012-12)
Results are presented from a search for a narrow, spin-2 resonance decaying into a pair of Z bosons, with one Z-boson decaying into leptons (e[superscript +]e[superscript −] or μ[superscript +]μ[superscript −]) and the ...
Search for a heavy gauge boson W' in the final state with an electron and large missing transverse energy in pp collisions at √s = 7 TeV
(Elsevier, 2011-02)
A search for a heavy gauge boson W′ has been conducted by the CMS experiment at the LHC in the decay channel with an electron and large transverse energy imbalance E[miss over T], using proton–proton collision data ...
Measurement of Jet Multiplicity Distributions in t[bar over t] Production in pp Collisions at √s = 7 TeV
(Springer-Verlag, 2014-08)
The normalised differential top quark-antiquark production cross section is measured as a function of the jet multiplicity in proton-proton collisions at a centre-of-mass energy of 7 TeV at the LHC with the CMS detector. ...
Searches for electroweak production of charginos, neutralinos, and sleptons decaying to leptons and W, Z, and Higgs bosons in pp collisions at 8 TeV
(Springer-Verlag, 2014-09)
earches for the direct electroweak production of supersymmetric charginos, neutralinos, and sleptons in a variety of signatures with leptons and W , Z , and Higgs bosons are presented. Results are based on a sample of ...
