论文摘要
我们研究了将来在$ l^\ pm+2j+2j+MET $最终选择IDM和MSSM的$ e^+e^ - collider $ e^+e^ - 碰撞器中识别自旋的性质的可能性。我们为质量参数选择四个基准，以与SM $ W^+W^ - $背景有重大偏差。我们发现，与纵向极化初始光束中的IDM信号相比，与$ JJ $ Pair构建的$ w $ boson的$ \cosθ$有可能识别MSSM信号。以$ W $玻色子和带电的Lepton的方位角角度的形状可以看到更加可靠的比较，如果横梁横向极化，可以进一步识别IDM信号。
We investigate the possibility to identify the nature of spin of exotic charged particles at the future $e^+e^-$ collider in $l^\pm+2j+MET$ final state choosing IDM and MSSM as examples for the new physics models with scalar and fermionic exotic charged particles, respectively. We choose four benchmarks for the mass parameters for a significant deviation from the SM $W^+W^-$ background. We find that the $\cosθ$ of $W$ boson constructed from $jj$ pair and lepton have the potential to identify the MSSM signal compared to the IDM signal in longitudinally polarized initial beams. A more robust comparison is seen in the shape of the azimuthal angle of the $W$ boson and charged lepton, which can identify the IDM signal further if the beams are transversely polarized.
