We present results on a search for a heavy charged vector boson, W', decaying to an electron-neutrino pair in p{bar p} collisions at {radical}s = 1.96 TeV using a data sample corresponding to an integrated luminosity of 205 pb{sup -1}. We found no evidence of this decay channel, and set 95% confidence level limits on the production cross section times branching fraction assuming the light neutrino. We also set the limit on the W' boson mass at M{sub W'}> 788 GeV/c{sup 2}, assuming the standard model strength couplings.

We present results on a search for a heavy charged vector boson, W', decaying to an electron-neutrino pair in p$ar{p}$ collisions at √s = 1.96 TeV using a data sample corresponding to an integrated luminosity of 205 pb-1. We found no evidence of this decay channel, and set 95% confidence level limits on the production cross section times branching fraction assuming the light neutrino. We also set the limit on the W' boson mass at MW' > 788 GeV/c2, assuming the standard model strength couplings.

The authors present the results of a search for W′ boson decaying to electron-neutrino pairs in p{bar p} collisions at a center-of-mass energy of 1.96 TeV, using a data sample corresponding to 205 pb−1 of integrated luminosity collected by the CDF II detector at Fermilab. They 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 they assume the manifest left-right symmetric model, they exclude a W′ boson with mass less than 788 GeV/c2 at the 95% confidence level.

The ATLAS detector at the LHC is used to search for heavy charged gauge bosons (W'), decaying to a charged lepton (electron or muon) and a neutrino. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 1.04 fb−1. No excess beyond Standard Model expectations is observed. A W' with Sequential Standard Model couplings is excluded at the 95% confidence level for masses up to 2.15 TeV.

We report the results of a search for the anomalous production of a massive particle decaying to four electrons via two Z° bosons in 1.1 fb−1 of p{bar p} collisions at √s =1.96 TeV collected by the CDF II detector at Fermilab. We employ optimized electron identification criteria to maximize acceptance and efficiency. We estimate the backgrounds in the invariant mass range 500-1000 GeV/c2 to be 0.028 ± 0.009 (stat) ± 0.011 (syst) events. We observe zero events in this search region. Assuming a Randall-Sundrum graviton production model, we set 95% CL limits on [sigma] x BF(G → Z°Z°)
