论文摘要
较轻的chargino，$ \widetildeχ_1^{\ pm} $，是近代最佳的Susy粒子（NLSP）的主要候选人。已经对ILC的$ \widetildeχ_1^{\ pm}进行了几项分析，在特定的模型点上进行了$成对生产，表明即使对于非常困难的情况，也可能进行检测和属性确定性。但是，最近尚未评估ILC的覆盖范围，以检测$ \widetildeχ_1^{\ pm} $ PAIP的生产。在这项研究中，在广泛的参数范围内评估了ILC的$ \widetildeχ_1^{\ pm} $对生产的横截面。目的是确定最低的横截面的条件，并将这些最坏情况的值与估计ILC处观察最轻的Charginos的横截面极限的估计。估计的限制是从LEP进行的研究中推断出来的，这也可以被视为最坏的情况，因为检测器和加速器技术的巨大进步是无视的
The lighter chargino, $\widetildeχ_1^{\pm}$, is a prime candidate to be the next-to-lightest SUSY particle (the NLSP). Several analyses of $\widetildeχ_1^{\pm}$ pair-production at the ILC, at specific model-points, have been performed, showing that detection and property-determination is possible, even for very difficult cases. However, no recent studies have evaluated the reach of the ILC to detect $\widetildeχ_1^{\pm}$ pair production in general. In this study, cross sections for $\widetildeχ_1^{\pm}$ pair production at the ILC were evaluated within a wide range of parameters. The aim was to determine the conditions for the lowest cross sections and compare these worst-case values with an estimation of the cross section limit for the observation of the lightest charginos at the ILC. The estimated limits were extrapolated from the studies performed at LEP, which can also be regarded as a worst-case scenario, since the tremendous advances in detector and accelerator technologies are disregarded
