The Spin-dependent Scattering of Boosted Dark Matter

Understand

Boosted dark matter provides a promising approach to probe the light dark matter, whose computational framework in the spin-independent scattering process is well developed.

• However, the spin-dependent one lacks a unified treatment.
• The novelty of this paper is to give the first comprehensive derivation of the cross-section for boosted dark matter in spin-dependent scattering.
• When the transfer momentum is sufficiently large, there is a sizable enhancement to the proton structure factor from the time component.
