在未来e+e线性对撞机上用单光子过程判别SUSY破缺模型

Discrimination of SUSY breaking models using single-photon processes at future e+e- linear colliders

Hieu Minh Tran, Tadashi Kon, Yoshimasa Kurihara

摘要:

我们研究了未来e+e线性对撞机上超对称模型框架下的单光子过程。根据最近的实验结果,考虑了电子和正电子束的最佳极化度,以提高信噪比,从而揭示了超对称性破缺模型之间可观察到的差异。最小超引力模型和最小SU(5)大统一模型作为例子进行了研究。我们看到,经过几年的模拟数据,从对撞机接收到的两个模型之间的单光子事件数量的差异将超过统计误差的三倍,这为我们探索哪种模型将在自然界中实现提供了可能性。计算结果对国际直线对撞机的未来运行具有很好的指导意义。

英文摘要:

We examine the single-photon processes in the frame work of supersymmetric models at future e+e- linear colliders. According to the recent experimental achievement, the optimistic polarization degrees for both electron and positron beams are taken into account to enhance the signal-to-noise ratio revealing the observable difference between supersymmetry breaking models. The minimal supergravity model and the minimal SU(5) grand unified model in gaugino mediation have been examined as examples. We see that after several years of accummulating data, the difference of the number of single-photon events between the two models received from the collider would be in excess of three times the statistical error, providing us the possibility to probe which model would be realized in nature. The result is well suitable for the future running of the International Linear Collider.
