Search for W' Bosons decaying to an electron and a neutrino with the D0 Detector

Abstract

This Letter describes the search for a new heavy charged gauge boson W' decaying into an electron and a neutrino. The data were collected with the D0 detector at the Fermilab Tevatron pp̅ Collider at √s=1.96 TeV, and correspond to an integrated luminosity of about 1fb^-1. Lacking any significant excess in the data in comparison with known processes, an upper limit is set on σW'x B(W'→ev), and a W' boson with mass below 1.00 TeV can be excluded at the 95% C.L., assuming standard-model-like couplings to fermions. This result significantly improves upon previous limits and is the most stringent to date.
