LHC的计量调解:现状与前景

Gauge Mediation at LHC: status and prospects

Simon Knapen, Diego Redigolo

摘要:

我们表明,预测的一般规范调解(GGM)与TeV尺度停止大大增加,一旦希格斯质量约束。最值得注意的结果是一个强大的下限的质量的胶子和右手的平方,和上限的希格斯诺质量。如果mu参数为正,则wino质量也从上方有界。这些限制放宽显着高信使规模,因此长寿命的NLSP在GGM的青睐。我们确定了一个小的一组最有前途的拓扑结构的中性子/sneutrino NLSP的情况下,估计目前的界限和高亮度LHC的灵敏度的影响。在高光度LHC中,Stau、Stop和sbottom NLSP场景可以被鲁棒地排除。

英文摘要:

We show that the predictivity of general gauge mediation (GGM) with TeV-scale stops is greatly increased once the Higgs mass constraint is imposed. The most notable results are a strong lower bound on the mass of the gluino and right-handed squarks, and an upper bound on the Higgsino mass. If the mu-parameter is positive, the wino mass is also bounded from above. These constraints relax significantly for high messenger scales and as such long-lived NLSPs are favored in GGM. We identify a small set of most promising topologies for the neutralino/sneutrino NLSP scenarios and estimate the impact of the current bounds and the sensitivity of the high luminosity LHC. The stau, stop and sbottom NLSP scenarios can be robustly excluded at the high luminosity LHC.
