Finite temperature contributions to cosmological constant

We reexamine the cosmological constant (CC) problem in a finite temperature setup and propose an intriguing possibility of carrying out perturbative analysis by employing renormalization scheme which renormalized Higgs mass (or resummed mass, to be more precise) is taken on order cosmic microwave background (CMB) temperature. Our proposal hinges fact that although physical value CC does not depend one’s scheme, whether or fine tuning involved does. The avoided sense process no longer requires finetuning. This achieved essentially scheme-independence quantity, turn assured bare perturbation theory. shifts peculiarity consequent series for (and other massive sectors Standard Model); interpreted as indicator new physics after expected mathematical structure scrutinized. Finite-temperature-induced complexification effective potential observed its interpretation given. A consistency check cosmology context suggested.
