SUMMARY
The discussion centers on the RG flow diagram presented in Peskin and Schroeder's Quantum Field Theory, specifically diagram 12.1 (b) on page 403. Participants clarify that the initial increase of the coupling constant to the right, followed by a decrease until it reaches the fixed point at zero, is a matter of perspective rather than a contradiction. Equation 12.28 indicates that as b approaches zero, the coupling constant decreases monotonically, affirming that the curves are indeed situated in the m² = 0 plane.
