Metastability of the false vacuum in a Higgs-seesaw model of dark energy

Krauss, Lawrence; Long, Andrew J

Description

In a recently proposed Higgs-seesaw model the observed scale of dark energy results from a metastable false vacuum energy associated with mixing of the standard model Higgs particle and a scalar associated with new physics at the scale of unification or the Planck scale. Here we address the issue of how to ensure metastability of this state over cosmological time. We consider new tree-level operators, the presence of a thermal bath of hidden sector particles, and quantum corrections to the...[Show more]
