Abstract

In this study, we conducted a search for dark matter using a part of the data recorded by the CMS experiment during run-I of the LHC in 2012 with a center of mass energy of 8 TeV and an integrated luminosity of 11.6 fb−1. These data were gathered from the CMS open data. Dark matter, in the framework of the simplified model (mono-Z ), can be produced from proton-proton collisions in association with a new hypothetical gauge boson, Z . Thus, the search was conducted in the dimuon plus large missing transverse momentum channel. One benchmark scenario of mono-Z , which is known as light vector, was used for interpreting the CMS open data. No evidence of dark matter was observed, and exclusion limits were set on the masses of dark matter and Z at 95% confidence level.
利用 CMS 开放数据,在 TeV 质子-质子对撞中搜索与衰变为二微子的重中性规玻色子相关的暗费米子候选粒子的产生* * Y. Mahmoud 感谢埃及英属哥伦比亚大学理论物理中心(CTP)为这项工作提供的持续的经济和科学支持。
在这项研究中,我们利用 CMS 实验在 2012 年大型强子对撞机运行 I 期间记录的部分数据对暗物质进行了搜索,这些数据的质心能量为 8 TeV,综合光度为 11.6 fb-1。这些数据来自CMS开放数据。在简化模型(mono-Z)的框架内,暗物质可以通过质子-质子对撞与一种新的假定规玻色子Z结合产生。在解释 CMS 公开数据时,使用了一种单 Z 的基准方案,即所谓的光矢量。没有观测到暗物质的证据,因此对暗物质和Z的质量设定了置信度为95%的排除限。
