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…
Precision decay rate calculations in quantum field theory
Anders Andreassen, David Farhi, William Frost +1
Tunneling in quantum field theory is worth understanding properly, not least because it controls the long term fate of our universe. There are however, a number of features of tunn…
A direct approach to quantum tunneling
Anders Andreassen, David Farhi, William Frost +1
The decay rates of quasistable states in quantum field theories are usually calculated using instanton methods. Standard derivations of these methods rely in a crucial way upon def…
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…
