Pen Phenomenologiccal study of Supersynmetric Models at colliders

我们研究了在未来的对撞机实验中探索最小超对称标准模型(MSSM)细节的可能性。在MSSM中，粒子预计将在未来的对撞机上产生，如CERN大型强子对撞机LHC，或未来的e^+e^-对撞机，其质心位于ITeV附近。软超对称性超对称超对称破缺参数的确定，或相当于s粒子质量和混合角的确定，对于区分超对称破缺机制是重要的，这是该模型的关键组成部分。在我们的论文中，我们讨论了未来e^+e^-对撞机的超对称物理，并获得并发表了以下结果。通过对标量tau(Tau)产生和衰变的精确测量，可以测量tau、tau yukawa耦合的弱的和内脏尺度的软破裂质量。这决定了tau2的肠道比例相互作用。可以精确地测量伽吉诺-标量费米子-费米子耦合g_&lt；x-&gt；。这种耦合与SUSY的规范耦合有关，因此是对称性的最终检验。对SUSY关系的偏离可以被识别为辐射修正。我们证明了标量夸克的质量可以通过测量g&lt；x-&gt；的辐射修正来确定。

We study the possibility to explore the details of minimal supersymmetric standard models(MSSM) in future collider experiments. In MSSM particles are predicted to be produced at future colliders such as CERN large hadron collider LHC, or future e^+ e^- colliders whose center of mass energy is around I TeV.The determination of soft supersymmetry SUSY breaking parameters, or equivalently, determination of masses and mixing angle of sparticles are important to discriminate the SUSY breaking mechanism, which is the key ingredient of the model.In our papers, we discuss SUSY physics at future e^+ e^- colliders and following results are obtained and published.1. Though the precision measurement of scalar tau (tau) production and decay, one can measure the weak and GUT scale soft breaking masses of tau, tau Yukawa coupling. This determines the GUT scale interaction of tau.2. The gaugino-scalar fermion -fermion coupling g_<x-> could be measured precisely. The coupling is related to gauge coupling by SUSY, therefore serves as the ultimate test of the symmetry.3. The deviation from the SUSY relation may be identified as radiative corrections. We demonstrate that the mass of scalar quark can be determined through the measurement of the radiative correction of the g_<x->
