Electromagnetic and gravitational decay of the Higgs boson
arXiv:hep-ph/0004156
Abstract
The decays of a scalar particle, of either parity, into two photons or into two gravitons are evaluated. The effective interactions are of the form or ; in particular, Higgs boson decay into gravitons cannot be adduced to an interaction , as has been recently claimed.
