Abstract
Self-interacting dark matter has been suggested in order to overcome the difficulties of the cold dark matter model on galactic scales. We argue that a scalar gauge singlet coupled to the Higgs boson, which could lead to an invisibly decaying Higgs boson, is an interesting candidate for this self-interacting dark matter particle. We also present estimates on the abundance of these particles today as well as the consequences to non-Newtonian forces.
