有效理论中中微子望远镜的暗物质信号

Dark matter signals at neutrino telescopes in effective theories

Riccardo Catena

摘要:

我们用中微子望远镜观测约束了单体暗物质-核子相互作用的有效理论。我们推导出排除限制的28耦合常数的理论,探索相互作用运营商以前考虑在暗物质直接检测,并使用新的核响应函数最近通过原子核结构计算。我们确定什么样的相互作用中微子望远镜优于目前的直接检测实验,并表明,氢不是最重要的元素,在排斥极限计算的大多数自旋相关的运营商。

英文摘要:

We constrain the effective theory of one-body dark matter-nucleon interactions using neutrino telescope observations. We derive exclusion limits on the 28 coupling constants of the theory, exploring interaction operators previously considered in dark matter direct detection only, and using new nuclear response functions recently derived through nuclear structure calculations. We determine for what interactions neutrino telescopes are superior to current direct detection experiments, and show that Hydrogen is not the most important element in the exclusion limit calculation for the majority of the spin-dependent operators.
