Abstract:

We present a measurement of the inclusive production cross section for Z bosons decaying to tau leptons in pp̄ collisions at s=1.96TeV. We use a channel with one hadronically-decaying and one electronically-decaying tau. This measurement is based on 350pb-1 of CDF Run II data. Using a sample of 504 opposite sign eτ events with a total expected background of 190 events, we obtain σ(pp̄→4Z)•B(Z→ττ)=264±23(stat) ±14(syst)±15(lumi)pb, in agreement with the next-to-next-to- leading order QCD prediction. This is the first CDF cross section measurement using hadronically-decaying taus in Run II. © 2007 The American Physical Society.

Abstract:

We present the results of a search for W′ boson decaying to electron-neutrino pairs in pp̄ collisions at a center-of-mass energy of 1.96 TeV, using a data sample corresponding to 205pb-1 of integrated luminosity collected by the CDF II detector at Fermilab. We observe no evidence for this decay mode and set limits on the production cross section times branching fraction, assuming the neutrinos from W′ boson decays to be light. If we assume the manifest left-right symmetric model, we exclude a W′ boson with mass less than 788GeV/c2 at the 95% confidence level. © 2007 The American Physical Society.
