Search for Right-Handed $$W$$ Bosons and Heavy $$W^\prime$$ in $$p\bar p$$ Collisions at $$\sqrt{s} =$$1.8 TeV
We report on a search for right-handed $$W$$ bosons ($$W_R$$). We used data collected with the D\O \ detector at the Fermilab Tevatron $$p\bar p$$ collider at $$\sqrt{s}=$$1.8 TeV to search for $$W_R$$ decays into an electron and a massive right-handed neutrino $$W_R~\pm \rightarrow e~\pm N_R$$. Using the inclusive electron data, we set mass limits independent of the $$N_R$$ decay: $$m_{W_R}>650$$ GeV/c$~2$ and $$m_{W_R}>720$$ GeV/c$~2$$ at the 95\% confidence level, valid for $$m_{N_R}<\frac{1}{2}m_{W_R}$ and $$m_{N_R} \ll m_{W_R}$$ respectively. The latter also represents a new lower limit on the mass of a heavy left-handed $$W$$ boson ($$W~\prime$$) decaying into $$e \nu$$. In addition, limits on $$m_{W_R}$$ valid for larger values of the $$N_R$$ mass are obtained assuming that $$N_R$$ decays to an electron and two jets.
