Search for a heavy vector boson decaying to two gluons in pp̅ collisions at √s=1.96 TeV
(American Physical Society, 2012-12)
We present a search for a new heavy vector boson Z[superscript ′] that decays to gluons. Decays to on-shell gluons are suppressed, leading to a dominant decay mode of Z[superscript ′]→g[superscript *]g. We study the case ...
Performance of τ-lepton reconstruction and identification in CMS
(IOP Publishing, 2012-01-01)
The performance of τ-lepton reconstruction and identification algorithms is studied using a data sample of proton-proton collisions at s = 7 TeV, corresponding to an integrated luminosity of 36 pb-1 collected with the CMS ...
Precise Measurement of the W-Boson Mass with the CDF II Detector
(American Physical Society, 2012-04)
We have measured the W-boson mass M[superscript W] using data corresponding to 2.2 fb[superscript -1] of integrated luminosity collected in pp̅ collisions at √s=1.96 TeV with the CDF II detector at the Fermilab Tevatron ...
Measurement of the branching fraction B(Λ[subscript b][superscript 0]→Λ[subscript c][superscript +]π[superscript -]π[superscript +]π[superscript -]) at CDF
(American Physical Society, 2012-02)
We report an analysis of the Λ[subscript b][superscript 0]→Λ[subscript c][superscript +]π[superscript -]π[superscript +]π[superscript -] decay in a data sample collected by the CDF II detector at the Fermilab Tevatron ...
Search for neutral Higgs bosons in events with multiple bottom quarks at the Tevatron
(American Physical Society, 2012-11)
The combination of searches performed by the CDF and D0 collaborations at the Fermilab Tevatron Collider for neutral Higgs bosons produced in association with b quarks is reported. The data, corresponding to 2.6 fb[superscript ...
Search for a Low-Mass Standard Model Higgs Boson in the ττ Decay Channel in pp̅ Collisions at √s=1.96 TeV
(American Physical Society, 2012-05)
We report on a search for the standard model Higgs boson decaying into pairs of τ leptons in pp̅ collisions produced by the Tevatron at √s=1.96 TeV. The analyzed data sample was recorded by the CDFII detector and corresponds ...
Search for the standard model Higgs boson decaying into two photons in pp collisions at √s = 7 TeV
(Elsevier B.V., 2012-04)
A search for a Higgs boson decaying into two photons is described. The analysis is performed using a dataset recorded by the CMS experiment at the LHC from pp collisions at a center-of-mass energy of 7 TeV, which corresponds ...
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 Higgs bosons produced in association with b quarks
(American Physical Society, 2012-01)
We present a search for neutral Higgs bosons ϕ decaying into bb̅ , produced in association with b quarks in pp̅ collisions. This process could be observable in supersymmetric models with high values of tanβ. The event ...
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). ...
