This study demonstrates that a naturally occurring MeV-scale dark matter candidate can arise through a warped extra dimension, with weak Higgs portal coupling and self-interaction coupling to address small-scale problems in the universe. The vast parameter space predicted within O(1) fundamental parameters supports this dark matter model.
A classically scale-invariant scalar singlet can be a MeV-scale dark matter, with a feeble Higgs portal coupling at O(10-10). Besides, an O(0.1) 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 O(1) fundamental parameters.
