    • Consistent use of effective potentials 

      Andreassen, Anders Johan; Frost, William Thomas; Schwartz, Matthew D (American Physical Society (APS), 2015)
      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 perturbation theory is not straightforward, since ...

    • Consistent Use of the Standard Model Effective Potential 

      Andreassen, Anders Johan; Frost, William Thomas; Schwartz, Matthew D (American Physical Society (APS), 2014)
      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 method is strongly dependent on the gauge ...
