On the trail of dark energy: Physicists propose Higgs boson 'portal'

One of the biggest mysteries in contemporary particle physics and cosmology is why dark energy, which is observed to dominate energy density of the universe, has a remarkably small (but not zero) value. This value is so small, it is perhaps 120 orders of magnitude less than would be expected based on fundamental physics. Resolving this problem, often called the cosmological constant problem, has so far eluded theorists. Now, two physicists -- Lawrence Krauss of Arizona State University and James Dent of the University of Louisiana-Lafayette -- suggest that the recently discovered Higgs boson could provide a possible "portal" to physics that could help explain some of the attributes of the enigmatic dark energy, and help resolve the cosmological constant problem.
