Quintessence saves Higgs instability
We study a model where quintessence potential e−ξϕ coupled to Higgs potential. We calculate the evolution of the quintessence, and track the running of the effective Higgs self coupling. We find it slightly larger than that of the standard model in the past. Requiring the electroweak vacuum to be ab...
