Received 21 December 1995; published in the issue dated 29 April 1996
We report on a search for right-handed W bosons (WR) with mass greater than 200GeV/c2. We used data collected with the D0 detector at the Fermilab Tevatron pp̅ collider at √s = 1.8TeV to search for WR decays into an electron and a massive right-handed neutrino WR±→e±NR. Using the inclusive electron data, we set mass limits independent of the NR decay: mWR>650GeV/c2 and mWR>720GeV/c2 at the 95% confidence level, valid for mNR<1/2mWR and mNR≪mWR, respectively. The latter also represents a new lower limit on the mass of a heavy left-handed W boson (W′) decaying into eν. In addition, limits on mWR valid for larger values of the NR mass are obtained assuming that NR decays to an electron and two jets.
