AI总结:

本文研究了银河系中心中子星群体捕获的暗物质通过长寿命媒介子湮灭产生中微子通量的情景,并发现IceCube/KM3NeT等千吨级探测器在TeV-PeV质量范围内的暗物质-核子散射截面探测上优于当前极限。

摘要:

分布在银河系中心周围的中子星群体捕获的粒子暗物质,通过长寿命媒介子湮灭,可产生可观测的中微子通量。我们考察了类似IceCube/KM3NeT的理想化千吨级探测器探测此类情景的前景。在此框架内,我们报告了在TeV-PeV质量范围内,自旋相关和自旋无关暗物质-核子散射截面超越了当前极限的改进探测范围。

英文摘要:

Particulate dark matter captured by a population of neutron stars distributed around the galactic center while annihilating through long-lived mediators can give rise to an observable neutrino flux. We examine the prospect of an idealised gigaton detector like IceCube/KM3NeT in probing such scenarios. Within this framework, we report an improved reach in spin-dependent and spin-independent dark matter nucleon cross-section below the current limits for dark matter masses in the TeV-PeV range.
