摘要:

LHC关于喷流和能量缺失的第一个结果为检验超对称模型提供了强有力的新数据。对这些数据的最初理论解释集中在重力调解上,通常是CMSSM及其变体。在本文中,我们面对一个大类的规范中介模型与这些新的数据。更确切地说,我们认为模型的纯一般规范调解(纯GGM),并面对他们最近的实验结果的ATLAS合作。我们使用Herwig++和RIVET,结合全套实验切割,计算信号速率并将其与数据进行比较。虽然基于只有35 pb ^{-1}的积分亮度,我们表明,这些新的数据探测和排除了一部分以前允许的参数空间的GGM。此外,我们调查的可行性标准超对称性基准点,包括斯诺马斯,CMS和ATLAS集,其中包括其他调解方案,如重力,异常和高吉诺调解。

英文摘要:

The first results from the LHC on jets plus missing energy provide powerful new data to test SUSY models. Initial theoretical interpretations of these data have concentrated on gravity mediation, usually the CMSSM and its variations. In this paper we confront a large class of gauge mediation models with these new data. More precisely we consider models of pure general gauge mediation (pure GGM) and confront them with the recent experimental results of the ATLAS collaboration. We use Herwig++ and RIVET, incorporating the full set of experimental cuts, to calculate the signal rates and compare them to the data. Although based on only 35pb^{-1} of integrated luminosity, we show that these new data probe and exclude a portion of previously allowed parameter space of GGM. In addition we investigate the viability of standard SUSY benchmark points, including the Snowmass, CMS and ATLAS sets which encompass other mediation scenarios such as gravity, anomaly and gaugino mediation.
