直接在LHC上测试Gaugino质量统一

Testing Gaugino Mass Unification Directly at the LHC

Brent D. Nelson

摘要:

我们报告的第一步,如何可以在大型强子对撞机在一个准模型独立的方式探测高吉诺质量统一的系统研究。在这里,我们把我们的注意力集中在理论上动机良好的海市蜃楼模式的高吉诺群众,一个单参数家庭的模型,其中普遍的(高尺度)高吉诺群众是一个极限情况。使用统计方法来优化我们的签名选择,我们到达三个合奏的观测目标的物理学的高吉诺部门,允许确定这个非普适性参数,而不重建个人的质量本征值或软超光速打破高吉诺质量本身。在这个受控的环境中,我们发现,大约80%的超对称参数空间将产生一个模型,我们的方法将检测非普适性的高吉诺质量部门在10%的水平与约10个反femptobarns的积分亮度。

英文摘要:

We report on the first step of a systematic study of how gaugino mass unification can be probed at the LHC in a quasi-model independent manner. Here we focus our attention on the theoretically well-motivated mirage pattern of gaugino masses, a one-parameter family of models of which universal (high scale) gaugino masses are a limiting case. Using a statistical method to optimize our signature selection we arrive at three ensembles of observables targeted at the physics of the gaugino sector, allowing for a determination of this non-universality parameter without reconstructing individual mass eigenvalues or the soft supersymmetry-breaking gaugino masses themselves. In this controlled environment we find that approximately 80% of the supersymmetric parameter space would give rise to a model for which our method will detect non-universality in the gaugino mass sector at the 10% level with approximately 10 inverse femptobarns of integrated luminosity.
