Detecting Bosonic Dark Matter with Neutron Stars

Understand

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.
