Dark matter self-interactions from spin-2 mediators

Abstract We propose a new mechanism for rendering dark matter self-interacting in the presence of a massive spin-2 mediator.The derived Yukawa-type potential for dark matter is independent of the spins of dark matter Sorting in the leading order of the momentum expansion, so are the resulting non-perturbative effects for the dark matter self-scatte
