中微子望远镜中惰性双态暗物质的信号

Signals of Inert Doublet Dark Matter in Neutrino Telescopes

Prateek Agrawal, Ethan M. Dolle, Christopher A. Krenke

摘要:

标准模型的一个最简单的扩展是惰性偶极子模型,它解释了观测到的暗物质的丰度。在这个理论中,一个离散的对称性确保了一个额外的电弱偶标量的中性分量是稳定的,并构成了一个暗物质候选者。当太阳和地球这样的大质量天体穿过暗物质晕时,暗物质粒子会被引力困在它们的核心。这些粒子的湮灭产生了中微子,这可以用中微子望远镜观察到。我们计算中微子的检测率在这些实验中从惰性的双重暗物质湮灭在太阳和地球的核心。

英文摘要:

One of the simplest extensions of the Standard Model that explains the observed abundance of dark matter is the inert doublet model. In this theory a discrete symmetry ensures that the neutral component of an additional electroweak doublet scalar is stable, and constitutes a dark matter candidate. As massive bodies such as the Sun and Earth move through the dark matter halo, dark matter particles can become gravitationally trapped in their cores. Annihilations of these particles result in neutrinos, which can potentially be observed with neutrino telescopes. We calculate the neutrino detection rate at these experiments from inert doublet dark matter annihilations in the cores of the Sun and the Earth.
