暗物质直接探测前沿的中子星

Neutron stars at the dark matter direct detection frontier

Nirmal Raj, Philip Tanedo, Hai-Bo Yu

摘要:

中子星有效地捕获了暗物质。在捕获过程中传递的动能加热了本地星系晕中的老中子星,使其温度达到即将到来的红外望远镜可以探测到的温度。我们推导出该探头的有效运营商的框架中的灵敏度。对于比GeV重的暗物质,我们发现,中子星加热可以设置有效的运营商截止的数量级强于可能从地面直接检测实验的情况下,自旋相关和速度抑制散射的限制。

英文摘要:

Neutron stars capture dark matter efficiently. The kinetic energy transferred during capture heats old neutron stars in the local galactic halo to temperatures detectable by upcoming infrared telescopes. We derive the sensitivity of this probe in the framework of effective operators. For dark matter heavier than a GeV, we find that neutron star heating can set limits on the effective operator cutoff that are orders of magnitude stronger than possible from terrestrial direct detection experiments in the case of spin-dependent and velocity-suppressed scattering.
