Gauge dependence of alternative flow equation for the functional renormalization group
Published 23 Mar 2020 in hep-th, math-ph, and math.MP | (2003.10079v3)
Abstract: The gauge dependence problem of alternative flow equation for the functional renormalization group is studied. It is shown that the effective two-particle irreducible effective action depends on gauges at any value of IR parameter $k$. The situation with gauge dependence is similar to the standard formulation based on the effective one-particle irreducible effective action.
