Search for a heavy vector boson decaying to two gluons in pp̄ collisions at √s=1.96TeV
Physical Review D - Particles, Fields, Gravitation and Cosmology 86:11 (2012)
Abstract:
We present a search for a new heavy vector boson Z′ that decays to gluons. Decays to on-shell gluons are suppressed, leading to a dominant decay mode of Z′→g*g. We study the case where the off-shell gluon g* converts to a pair of top quarks, leading to a final state of tt̄g. In a sample of events with exactly one charged lepton, large missing transverse momentum and at least five jets, corresponding to an integrated luminosity of 8.7fb-1 collected by the CDF II detector, we find the data to be consistent with the standard model. We set upper limits on the production cross section times branching ratio of this chromophilic Z′ at 95% confidence level from 300 to 40 fb for Z′ masses ranging from 400 to 1000GeV/c2, respectively. © 2012 American Physical Society.Measurements of the top-quark mass and the tt̄ cross section in the hadronic τ+jets decay channel at √s=1.96TeV

Abstract:
We present the first direct measurement of the top-quark mass using tt̄ events decaying in the hadronic τ+jets decay channel. Using data corresponding to an integrated luminosity of 2.2fb -1 collected by the CDF II detector in pp̄ collisions at √s=1.96TeV at the Fermilab Tevatron, we measure the tt̄ cross section, σ tt̄, and the top-quark mass, M top. We extract M top from a likelihood based on per-event probabilities calculated with leading-order signal and background matrix elements. We measure σ tt̄=8. 8±3.3(stat)±2.2(syst)pb and M top=172.7±9.3(stat) ±3.7(syst)GeV/c2. © 2012 American Physical Society.Search for neutral Higgs bosons in events with multiple bottom quarks at the Tevatron
