次世代電子陽電子加速器におけるトップクォーク生成過程を用いた超対称性理論模型の検証

Abstract

We investigate the top quark pair production at the next electron-positron linear colliders in the framework of the minimal supersymmetric standard model (MSSM). Typical two parameter sets (scenarios), which are consistent with all experimental constraints, are proposed. Both differential and total cross sections of the top quark pair production at 1-loop order are calculated for the two scenarios. We discuss possibilities for discovery of the signal of supersymmetry as well as for discrimination between the scenarios using the physical observables.
