摘要：

We report on a search for right-handed W bosons (W-R) with mass greater than 200 GeV/c(2). We used data collected with the DO detector at the Fermilab Tevatron p (p) over bar collider at root s = 1.8 TeV to search for W-R decays into an electron and a massive right-handed neutrino W-R(+/-) --> e(+/-)N(R). Using the inclusive electron data, we set mass limits independent of the N-R decay: m(WR) > 650 GeV/c(2) and m(WR) > 720 GeV/c(2) at the 95% confidence level, valid for m(NR) < 1/2-m(WR) << m(WR), respectively. The latter also represents a new lower limit on the mass of a heavy left-handed W boson (W-') decaying into e nu. In addition, limits on m(WR) valid for larger values of the N-R mass are obtained assuming that NR decays to an electron and two jets.
