Search for Wprime Boson Decaying to Electron-Neutrino Pairs in pbarp Collisions at sqrt{s}=1.96 TeV

TL;DR

This paper reports a search for Wprime bosons decaying into electron-neutrino pairs in proton-antiproton collisions at 1.96 TeV, setting mass exclusion limits based on the collected data.

Contribution

First search for Wprime boson decaying to electron-neutrino pairs at Tevatron energies, establishing new mass exclusion limits under specific model assumptions.

Findings

No evidence for Wprime boson decay observed.

Excluded Wprime boson masses below 788 GeV/c^2 at 95% confidence level.

Set upper limits on production cross section times branching fraction.

Abstract

We present the results of a search for Wprime boson decaying to electron-neutrino pairs in pbarp 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. We observe no evidence for this decay mode and set limits on the production cross section times branching fraction, assuming the neutrinos from Wprime boson decays to be light. If we assume the manifest left-right symmetric model, we exclude a Wprime boson with mass less than 788 GeV/c^2 at the 95% confidence level.
