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 pp collider at √(s)\phantom\rule0ex0ex=\phantom\rule0ex0ex1.8TeV to search for WR decays into an electron and a massive right-handed neutrino WR^\ifmmode±\else\textpm\fi\ensuremath→e^\ifmmode±\else\textpm\fiNR. Using the inclusive electron data, we set mass limits independent of the NR decay: m_WR>650GeV/c2 and m_WR>720GeV/c2 at the 95% confidence level, valid for m_NR<(1)/(2)m_WR and m_NR\ensuremath≪m_WR, respectively. The latter also represents a new lower limit on the mass of a heavy left-handed W boson (W^\ensuremath') decaying into e\ensuremathν. In addition, limits on m_WR valid for larger values of the NR mass are obtained assuming that NR decays to an electron and two jets.
