With the addition of supersymmetry the three running . One can search for solutions of the FRGE rather than evaluate the path integral (1) directly. For a discussion of this, most paper point to Shifman and Vainshtein's paper, “Solution of the anomaly puzzle inSUSY gauge theories and the Wilson operator expansion.” [doi:10.1016/0550-3213(86)90451-7]. It is a theory where couplings run according to the Wilsonian RG flow, i.e. We still have to perform the path integral. Since its early days it has been understood that it improves the naturalness of low energy particle physics due to anomaly cancellations that help keep the Higgs sector light. This book introduces the quantum mechanics of particles moving in curved space by employing path integrals and then using them to compute anomalies in quantum field theories. It's worth noting that To be explicit, the Wilsonian action is a theory with a cutoff. Once he understands them, he must be completely sure that as quantum variables, i.e. As integration variables in a path integral, they're exactly as consistent as the commuting variables. It is a theory that we still have to treat quantum mechanically.
