Nucleosynthesis bounds on a time-varying cosmological 'constant'

Astrophysics 2011-02-16 v3 High Energy Physics - Phenomenology

Abstract

We constrain proposed phenomenological models for a vacuum energy which decays with the expansion of the universe from considerations of standard big bang nucleosynthesis. Several such models which attempt to solve the cosmological age problem are disfavored or even ruled out.
