分享但不关心：对撞机现象学
Sharing but not Caring: Collider Phenomenology
摘要：
基于以前的工作场景中的标准模型和暗物质粒子共享一个共同的不对称性，通过有效的运营商在宇宙的早期，后来从彼此去耦（不关心），在这项工作中，我们详细研究了这些场景的对撞机现象。特别地，我们使用大型强子对撞机（LHC）的实验结果来约束可行的参数空间。除了有效算子外，我们还利用LHC和大型正负电子对撞机的实验结果对一些典型的紫外完备模型的参数空间进行了约束。具体而言，我们使用与射流+缺失横向能量（MET）、双射流和光子+ MET相关的测量。在紫外线模型的情况下，根据对介质的耦合和质量的假设，导出的约束可以变得或多或少严格。我们还考虑的情况下，其中一个介质的质量低于100 GeV，在这种情况下，我们使用紫外线模型来构建一个新的有效的运营商负责共享的不对称性，并研究其现象。
英文摘要：
Based on a previous work on scenarios where the Standard Model and dark matter particles share a common asymmetry through effective operators at early time in the Universe and later on decouple from each other (not care), in this work, we study in detail the collider phenomenology of these scenarios. In particular, we use the experimental results from the Large Hadron Collider (LHC) to constrain the viable parameter space. Besides effective operators, we also constrain the parameter space of some representative ultraviolet complete models with experimental results from both the LHC and the Large Electron-Positron Collider. Specifically, we use measurements related to jets + missing transverse energy (MET), di-jets and photon + MET. In the case of ultraviolet models, depending on the assumptions on the couplings and masses of mediators, the derived constraints can become more or less stringent. We consider also the situation where one of the mediators has mass below 100 GeV, in this case we use the ultraviolet model to construct a new effective operator responsible for the sharing of the asymmetry and study its phenomenology.
