摘要:

在寻找宇宙中的暗物质(DM)成分的过程中,对丢失能量的碰撞事件的研究是LHC寻找新物理的广泛计划的重要组成部分。鉴于DM的未知性质,对此类检索的解释应具有广泛性和包容性。本报告回顾了在解释缺失能量搜索时使用简化模型的情况。我们首先简要地讨论了有效场论方法对这个问题的实用性和局限性。然后,报告的大部分内容将致力于几种不同的简化模型及其签名,包括s通道和t通道过程。DM的简化模型的一个共同特征是存在额外的粒子,这些粒子介导了标准模型和组成DM的粒子之间的相互作用。我们详细地考虑了这些,并强调在任何连贯的解释中将它们作为最终状态包括在内的重要性。我们还回顾了一些在该领域的实验进展,新的签名,和其他方面的搜索本身。最后,我们的意见和建议,使用简化模型运行II的大型强子对撞机。

英文摘要:

The study of collision events with missing energy as searches for the dark matter (DM) component of the Universe are an essential part of the extensive program looking for new physics at the LHC. Given the unknown nature of DM, the interpretation of such searches should be made broad and inclusive. This report reviews the usage of simplified models in the interpretation of missing energy searches. We begin with a brief discussion of the utility and limitation of the effective field theory approach to this problem. The bulk of the report is then devoted to several different simplified models and their signatures, including s-channel and t-channel processes. A common feature of simplified models for DM is the presence of additional particles that mediate the interactions between the Standard Model and the particle that makes up DM. We consider these in detail and emphasize the importance of their inclusion as final states in any coherent interpretation. We also review some of the experimental progress in the field, new signatures, and other aspects of the searches themselves. We conclude with comments and recommendations regarding the use of simplified models in Run-II of the LHC.
