Rizzo, T G

While the much discussed lepton-number violating process e{sup {minus}}e{sup {minus}} {yields} W{sub R}{sup {minus}}W{sub R}{sup {minus}} 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 W{sub R}`s are too massive to be pair produced at the NLC with {radical}s in the 1-1.5 TeV range. The author is thus lead to consider the single W{sub R} production process e{sup {minus}}e{sup {minus}} {yields} W{sub R}{sup {minus}}(W{sub R}{sup {minus}}){sup *} {yields} W{sub R}{sup {minus}} + jj in order to expand the collider`s kinematic reach. After pointing out that W{sub R}`s with masses of order 1 TEV may be missed by future hadron collider searches, the author demonstrates that this three-body process possesses a significant cross section, of order several fb, at the NLC with {radical}s in the range above. The angular distribution of the produced W{sub R}`s is shown to be essentially flat and the potential backgrounds from standard model processes are shown to be small.
