Abstract

While the much discussed lepton-number violating process eeWRWRe^-e^-\rightarrow W_R^-W_R^- provides an excellent probe of both the Majorana nature of the right-handed neutrino and the symmetry breaking sector of the Left-Right Symmetric Model, it is likely that WRW_R's are too massive to be pair produced at the NLC with s\sqrt {s} in the 1-1.5 TeV range. We are thus lead to consider the single WRW_R production process eeWR(WR)WR+jje^-e^-\rightarrow W_R^-(W_R^-)^* \rightarrow W_R^-+jj in order to expand the collider's kinematic reach. After pointing out that WRW_R's with masses of order 1 TeV may be missed by future hadron collider searches, we demonstrate that this three-body process possesses a significant cross section, of order several fb, at the NLC with s\sqrt {s} in the range above. The angular distribution of the produced WRW_R's is shown to be essentially flat and the potential backgrounds from standard model processes are shown to be small.
