Freeze-in self-interacting dark matter in warped extra dimension
arXiv:2101.00618 · doi:10.1016/j.physletb.2021.136566
Abstract
A classically scale-invariant scalar singlet can be a MeV-scale dark matter, with a feeble Higgs portal coupling at . Besides, an self-interaction coupling could further serve to alleviate the small-scale problems in the Universe. We show that, such a dark matter candidate can naturally arise in the warped extra dimension, with the huge span of parameter space predicted well within fundamental parameters.
