Scale Invariant Instantons and the Complete Lifetime of the Standard Model
Anders Andreassen, William Frost, Matthew D. Schwartz
In a classically scale-invariant quantum field theory, tunneling rates are infrared divergent due to the existence of instantons of any size. While one expects such divergences to…
Consistent Use of the Standard Model Effective Potential
Anders Andreassen, William Frost, Matthew D. Schwartz
The stability of the Standard Model is determined by the true minimum of the effective Higgs potential. We show that the potential at its minimum when computed by the traditional m…
Consistent Use of Effective Potentials
Anders Andreassen, William Frost, Matthew D. Schwartz
It is well known that effective potentials can be gauge-dependent while their values at extrema should be gauge-invariant. Unfortunately, establishing this invariance in perturbati…
