Search for dark matter and large extra dimensions in monojet events in pp collisions at √s = 7 TeV
(Springer Nature, 2012-09)
A search has been made for events containing an energetic jet and an imbalance in transverse momentum using a data sample of pp collisions at a center-of-mass energy of 7 TeV. This signature is common to both dark matter ...
Measurement of the tt̅ production cross section in pp collisions at √s=7 TeV in dilepton final states containing a τ
(American Physical Society, 2012-06)
The top quark pair production cross section is measured in dilepton events with one electron or muon, and one hadronically decaying τ lepton from the decay tt̅ →(ℓν[subscript ℓ])(τ[subscript h]ν[subscript τ])bb̅ , (ℓ=e,μ). ...
Inclusive search for squarks and gluinos in pp collisions at √s=7 TeV
(American Physical Society, 2012-01)
A search is performed for heavy particle pairs produced in √s=7 TeV proton-proton collisions with 35 pb[superscript -1] of data collected by the CMS experiment at the LHC. The search is sensitive to squarks and gluinos ...
Search for New Physics with Same-Sign Isolated Dilepton Events with Jets and Missing Transverse Energy
(American Physical Society, 2012-08)
A search for new physics is performed in events with two same-sign isolated leptons, hadronic jets, and missing transverse energy in the final state. The analysis is based on a data sample corresponding to an integrated ...
Performance of CMS muon reconstruction in pp collision events at √s = 7 TeV
(IOP Publishing, 2012-10)
The performance of muon reconstruction, identification, and triggering in CMS has been studied using 40 pb⁻¹ of data collected in pp collisions at √s = 7 TeV at the LHC in 2010. A few benchmark sets of selection criteria ...
Search for physics beyond the standard model in events with a Z boson, jets, and missing transverse energy in pp collisions at √s =7 TeV
(Elsevier B.V., 2012-09)
A search is presented for physics beyond the standard model (BSM) in events with a Z boson, jets, and missing transverse energy (Emiss[over]T) This signature is motivated by BSM physics scenarios, including supersymmetry. ...
Measurement of the t[bar over t] production cross section in the dilepton channel in pp collisions at √s =7 TeV
(Springer Nature, 2012-11)
The t[bar over t] over bar production cross section (σ[subscript t[bar pver t]) over bar)) is measured in proton-proton collisions at root √s = 7 TeV in data collected by the CMS experiment, corresponding to an integrated ...
Measurement of the rapidity and transverse momentum distributions of Z bosons in pp collisions at √(s)=7 TeV
(American Physical Society, 2012-02)
Measurements of the normalized rapidity (y) and transverse-momentum (q[subscript T]) distributions of Drell–Yan muon and electron pairs in the Z-boson mass region (60<M[subscript ℓℓ]<120 GeV) are reported. The results are ...
Search for charge-asymmetric production of W' bosons in t[bar over t] + jet events from pp collisions at √s = 7 TeV
(Elsevier, 2012-09)
A search is presented for charge-asymmetric production of a W′ boson that has been proposed to accommodate the forward–backward asymmetry observed in the production of top–antitop quark pairs at the Tevatron. The new heavy ...
Search for the Standard Model Higgs Boson in the Decay Channel H→ZZ→4l in pp Collisions at √s=7 TeV
(American Physical Society, 2012-03)
A search for a Higgs boson in the four-lepton decay channel H→ZZ, with each Z boson decaying to an electron or muon pair, is reported. The search covers Higgs boson mass hypotheses in the range of 110<m[subscript H]<600 GeV. ...
