On the fate of the Standard Model at finite temperature

Understand

In this paper we revisit and update the computation of thermal corrections to the stability of the electroweak vacuum in the Standard Model.

• At zero temperature, we make use of the full two-loop effective potential, improved by three-loop beta functions with two-loop matching conditions.
• At finite temperature, we include one-loop thermal corrections together with resummation of daisy diagrams.
• We solve numerically---both at zero and finite temperature---the bounce equation, thus providing an accurate description of the thermal tunneling.
