The higgs boson is where mass comes from. Mass and its associated gravitational field is what slows down the expansion of the universe. So far, gravity is well understood and no observations have called into question our understanding of gravity yet.
The acceleration of the expansion of the universe is new, and that's what they're saying is caused by dark energy. So that's something else. Dark energy is something that seems to produce more space.
