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 pp-bar Collider at s√=1.96 TeV, and correspond to an integrated luminosity of about 1 fb(−1). Lacking any significant excess in the data in comparison with known processes, an upper limit is set on σ(W′)×B((W′)→eν), 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.
