暗物质与自旋为1介质的标准模型相互作用的有效场论分析

Effective field theory analysis of dark matter-standard model interactions with spin one mediators

Fabiola Fortuna, Pablo Roig, José Wudka

摘要:

我们在有效场论框架下分析了暗物质与自旋为1的标准模型粒子的相互作用。在本文中,我们考虑暗粒子的质量范围从几兆电子伏的质量的$Z$玻色子。我们使用不同的实验的界限:$Z$不可见的衰变宽度,遗迹密度,直接检测实验,和间接的探测极限从伽马射线发射和正电子通量的搜索。我们得到的解决方案对应的运营商与反对称张量介质,满足所有这些要求,在我们的方法。

英文摘要:

We analyze interactions between dark matter and standard model particles with spin one mediators in an effective field theory framework. In this paper, we are considering dark particles masses in the range from a few MeV to the mass of the $Z$ boson. We use bounds from different experiments: $Z$ invisible decay width, relic density, direct detection experiments, and indirect detection limits from the search of gamma-ray emissions and positron fluxes. We obtain solutions corresponding to operators with antisymmetric tensor mediators that fulfill all those requirements within our approach.
