Decay Rate of Electroweak Vacuum in the Standard Model and Beyond

Understand

We perform a precise calculation of the decay rate of the electroweak vacuum in the standard model as well as in models beyond the standard model.

• We use a recently-developed technique to calculate the decay rate of a false vacuum, which provides a gauge invariant calculation of the decay rate at the one-loop level.
• We give a prescription to take into account the zero modes in association with translational, dilatational, and gauge symmetries.
• We calculate the decay rate per unit volume, $\gamma$, by using an analytic formula.
