Gauge dependence of alternative flow equation for the functional renormalization group
arXiv:2003.10079 · doi:10.1016/j.nuclphysb.2020.115107
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 . The situation with gauge dependence is similar to the standard formulation based on the effective one-particle irreducible effective action.
