Abstract

We investigate to which extent the SUSY search results published by ATLAS and CMS in the context of simplified models actually cover the more realistic scenarios of a full model. Concretely, we work within the phenomenological MSSM (pMSSM) with 19 free parameters and compare the constraints obtained from SModelS v1.1.1 with those from the ATLAS pMSSM study in arXiv:1508.06608. We find that about 40-45% of the points excluded by ATLAS escape the currently available simplified model constraints. For these points we identify the most relevant topologies which are not tested by the current simplified model results. In particular, we find that topologies with asymmetric branches, including 3-jet signatures from gluino-squark associated production, could be important for improving the current constraining power of simplified models results. Furthermore, for a better coverage of light stops and sbottoms, constraints for decays via heavier neutralinos and charginos, which subsequently decay visibly to the lightest neutralino are also needed.

摘要

我们研究了ATLAS和CMS在简化模型背景下发布的超对称搜索结果在多大程度上实际涵盖了完整模型的更现实情景。具体而言，我们在具有19个自由参数的唯象最小超对称标准模型（pMSSM）中开展工作，并将从SModelS v1.1.1获得的约束与来自arXiv:1508.06608中ATLAS的pMSSM研究所得的约束进行比较。我们发现，被ATLAS排除的点中约40 - 45%逃脱了当前可用的简化模型约束。对于这些点，我们确定了当前简化模型结果未测试的最相关拓扑结构。特别是，我们发现具有不对称分支的拓扑结构，包括胶微子 - squark关联产生的三喷注特征，对于提高当前简化模型结果的约束能力可能很重要。此外，为了更好地覆盖轻stop和sbottom，还需要对通过较重中性超对称粒子和带电超对称粒子衰变的约束，这些粒子随后会明显衰变为最轻的中性超对称粒子。
