Self-interacting dark matter and the Higgs boson - art. no. 041302

Self-interacting dark matter has been suggested in order to overcome the di fficulties 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 i nvisibly decaying Higgs boson, is an interesting candidate for this self-in teracting dark matter particle. We also present estimates on the abundance of these particles today as well as the consequences to non-Newtonian force s.
