Inclusive and differential measurements of the t[bar over t] charge asymmetry in proton-proton collisions at √s = 7 TeV
(Elsevier, 2012-09)
The t[bar over t] charge asymmetry is measured in events containing a charged lepton (electron or muon) and at least four jets, one of which is identified as originating from b-quark hadronization. The analyzed dataset ...
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 inclusive production cross sections for forward jets and for dijet events with one forward and one central jet in pp collisions at √s = 7 TeV
(Springer-Verlag, 2012-06)
The inclusive production cross sections for forward jets, as well for jets in dijet events with at least one jet emitted at central and the other at forward pseudorapidities, are measured in the range of transverse momenta ...
Measurement of the single-top-quark t-channel cross section in pp collisions at √s = 7 TeV
(Springer Nature, 2012-12)
A measurement of the single-top-quark t-channel production cross section in pp collisions at √s=7 TeV with the CMS detector at the LHC is presented. Two different and complementary approaches have been followed. The first ...
A search for a doubly-charged Higgs boson in pp collisions at √s = 7 TeV
(Springer Nature, 2012-11)
A search for a doubly-charged Higgs boson in pp collisions at √s=7 TeV is presented. The data correspond to an integrated luminosity of 4. 9 fb[superscript -1], collected by the CMS experiment at the LHC. The search is ...
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 supersymmetry in events with b-quark jets and missing transverse energy in pp collisions at 7 TeV
(American Physical Society, 2012-10)
Results are presented from a search for physics beyond the standard model based on events with large missing transverse energy, at least three jets, and at least one, two, or three b-quark jets. The study is performed using ...
Study of the Dijet Mass Spectrum in pp→W+jets Events at √s=7 TeV
(American Physical Society, 2012-12)
We report an investigation of the invariant mass spectrum of the two jets with highest transverse momentum in pp→W+2-jet and W+3-jet events to look for resonant enhancement. The data sample corresponds to an integrated ...
Measurement of the mass difference between top and antitop quarks
(Springer-Verlag, 2012-06)
A measurement of the mass difference between the top and the antitop quark (Δm [subscript t] = m [subscript t] − m[¯ over t] ) is performed using events with a muon or an electron and at least four jets in the final state. ...
Measurement of the relative prompt production rate of χ[subscript c2] and χ[subscript c1] in pp collisions at √s = 7TeV
(Springer-Verlag, 2012-11)
A measurement is presented of the relative prompt production rate of χ[subscript c2] and χ[subscript c1] with 4.6 fb[superscript −1] of data collected by the CMS experiment at the LHC in pp collisions at √s = 7 TeV. The ...
