The nature of dark matter (DM) is one of the most pressing and unresolved questions in elementary particle physics. An attractive explanation for dark matter is a new, massive elementary particle with weak couplings to Standard Model (SM) particles. If this is the case it is reasonable to assume that the Higgs boson, which couples to mass, could decay to a pair of DM particles in an "invisible decay". The aim of this project is to search for invisible Higgs decays in the full LHC Run-II dataset collected by CMS and preparing searches for LHC Run-III. In order to maximise sensitivity to to invisible Higgs decays this project aims to carry out an analysis that covers all SM Higgs production processes with a consistent systematic treatment of all channels.

暗物质（DM）的性质是基本粒子物理学中最紧迫和尚未解决的问题之一。对暗物质的一个有吸引力的解释是一种新的、大质量的基本粒子，与标准模型（SM）粒子有弱耦合。如果是这样的话，那么可以合理地假设与质量耦合的希格斯玻色子可以在“不可见的衰变”中衰变为一对DM粒子。该项目的目的是在CMS收集的完整LHC Run-II数据集中搜索不可见的希格斯衰变，并为LHC Run-III的搜索做准备。为了最大限度地提高对不可见希格斯衰变的敏感性，该项目旨在进行一项分析，涵盖所有SM希格斯的生产过程，并对所有通道进行一致的系统处理。
