利用中子星探测玻色子暗物质

Detecting Bosonic Dark Matter with Neutron Stars

Tarak Nath Maity, Farinaldo S Queiroz

摘要:

如果暗物质-核子散射截面太小,无法通过直接探测实验探测到,那会怎样?众所周知,在文献中,一些相互作用导致暗物质-核子散射截面,可以被速度和动量抑制。我们表明,在玻色子暗物质的情况下,中子星光谱提供了一个可能的检测。首先,我们讨论了标量暗物质与标量,赝标量和矢量介质的情况。稍后,我们将对矢量暗物质做这个练习。我们发现,根据暗物质的性质和相互作用,中子星可以提高灵敏度的暗物质-核子散射截面的数量级,代表了一个重大的进步,在暗物质围攻。

英文摘要:

What if the dark matter-nucleon scattering cross section is too small to be detected by direct detection experiments? It is well known in the literature that some interactions lead to dark matter-nucleon scattering cross sections that can be velocity and momentum suppressed. We show that in the case of bosonic dark matter, neutron star spectroscopy offers a possible detection. Firstly, we discuss the case of scalar dark matter with scalar, pseudoscalar, and vector mediators. Later, we do this exercise for vector dark matter. We show that, depending on the nature of dark matter and the interaction involved, neutron stars can improve the sensitivity on the dark matter-nucleon scattering cross section by orders of magnitude, representing a major step forward in the dark matter siege.
