标题： Extending the Kinematic Range for $W_R$ Searches in $e^-e^-$ Collisions at the NLC

摘要： 虽然被广泛讨论的轻子数破坏过程$e^-e^-\rightarrow W_R^-W_R^-$为研究右手中微子的马约拉纳性质以及左右对称模型的对称性破缺区提供了极好的探测手段，但$W_R$的质量可能太大，无法在 NLC 中与$\sqrt {s}$在 1-1.5 TeV 范围内成对产生。因此，我们考虑单个$W_R$的产生过程$e^-e^-\rightarrow W_R^-(W_R^-)^* \rightarrow W_R^-+jj$，以扩展对撞机的运动学范围。在指出未来强子对撞机搜索可能会忽略质量约为 1 TeV 的$W_R$后，我们证明了在 NLC 中，上述范围内的$\sqrt {s}$具有显著的截面，约为几 fb。 产生的$W_R$的角分布显示基本上是平坦的，标准模型过程的潜在背景也被显示为很小。 显示英文摘要

摘要： While the much discussed lepton-number violating process $e^-e^-\rightarrow W_R^-W_R^-$ 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 $W_R$'s are too massive to be pair produced at the NLC with $\sqrt {s}$ in the 1-1.5 TeV range. We are thus lead to consider the single $W_R$ production process $e^-e^-\rightarrow W_R^-(W_R^-)^* \rightarrow W_R^-+jj$ in order to expand the collider's kinematic reach. After pointing out that $W_R$'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 $\sqrt {s}$ in the range above. The angular distribution of the produced $W_R$'s is shown to be essentially flat and the potential backgrounds from standard model processes are shown to be small.
