Search for scalar top quark production in p[bar over p] collisions at √s = 1.96 TeV
(Springer-Verlag, 2012-10)
We report on a search for the supersymmetric partner of the top quark (scalar top) decaying into a charm quark and a neutralino in p[¯ over p] collisions at √s = 1.96 TeV. The data sample, collected by the CDF II detector ...
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. ...
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 ...
Observation of Sequential Υ Suppression in PbPb Collisions
(American Physical Society, 2012-11)
The suppression of the individual Υ(nS) states in PbPb collisions with respect to their yields in pp data has been measured. The PbPb and pp data sets used in the analysis correspond to integrated luminosities of ...
An additional study of multi-muon events produced in pp̅ collisions at √s = 1.96 TeV
(Elsevier B.V., 2012-04)
We present one additional study of multi-muon events produced at the Fermilab Tevatron collider and recorded by the CDF II detector. We use a data set acquired with a dedicated dimuon trigger and corresponding to an ...
Search for the Standard Model Higgs Boson Produced in Association with Top Quarks Using the Full CDF Data Set
(American Physical Society, 2012-11)
A search is presented for the standard model Higgs boson produced in association with top quarks using the full Run II proton-antiproton collision data set, corresponding to 9.45 fb[superscript -1], collected by the ...
Search for Supersymmetry in Events with Photons and Low Missing Transverse Energy in pp Collisions at √s = 7 TeV
(Elsevier, 2012-12)
Many models of new physics, including versions of supersymmetry (SUSY), predict production of events with low missing transverse energy, electroweak gauge bosons, and many energetic final-state particles. The stealth SUSY ...
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 ...
Measurement of the Z/γ* + b-jet cross section in pp collisions at √s = 7 TeV
(Springer Nature, 2012-06)
The production of b jets in association with a Z/γ*boson is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7TeV and recorded by the CMS detector. The inclusive cross section for ...
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 ...
