如果LHC在sqrt(s)=7 TeV运行中没有发现超对称性,那会怎么样?

摘要:

我们研究了假设在7 TeV质心能量和1 ~ 7 fb^(-1)的积分亮度下LHC数据的第一周期中没有任何信号的超对称性的含义。我们考虑零轻子加四个喷流和丢失的横向能量信号,并在一个最小的超引力模型内进行低能测量,暗物质遗迹密度约束和潜在的LHC排除的组合拟合。在大型强子对撞机数据采集的第一阶段没有观测到超对称性,仍然可以用最小的超引力模型来描述低能数据和暗物质遗迹密度,但将排除质量低于1 TeV的夸克和胶子。

英文摘要:

We investigate the implications for supersymmetry from an assumed absence of any signal in the first period of LHC data taking at 7 TeV center-of-mass energy and with 1 to 7 fb^(-1) of integrated luminosity. We consider the zero-lepton plus four jets and missing transverse energy signature, and perform a combined fit of low-energy measurements, the dark matter relic density constraint and potential LHC exclusions within a minimal supergravity model. A non-observation of supersymmetry in the first period of LHC data taking would still allow for an acceptable description of low-energy data and the dark matter relic density in terms of minimal supergravity models, but would exclude squarks and gluinos with masses below 1 TeV.
