The interesting feature of this result is that, contrary to similar expressions for quantum electrodynamics [Eq. (13-29)] or <p4 theory [Eq. (13-79)J, P(g) has a sign opposite to g as g -4 0 (provided Tj < C). We shall later see the importance of this remark. The computation of anomalous dimensions is a priori of interest only for gauge invariant operators. We will also have to return to this point.

13-3 SCALE INV ARIANCE RECOVERED 13-3-1 Coupling Constant Flow
The exact equation of Callan and Symanzik finds its most interesting applications when the right-hand side involving the mass insertion may be neglected. If it were not the case we would have to face a cascade of functionals 1, 1 d , 1M,." containing the full complexity of the amplitudes throughout their kinematical domains. Here we are only interested in the deep euclidean regime where all momenta become large. This is, of course, only meaningful with respect to some mass scale. The Weinberg theorem of Chap. 8 comes to the rescue here. Its application to a strictly renormalizable theory shows that perturbatively 1,r) in (13-71) is depressed by a power p2 (up to logarithms) witlvtespect to the lefthand side. Therefore the massless limit of the theory exists provided normalization conditions at nonzero momentum be chosen. This offers the choice of an energy scale. Henceforth n~) will denote the corresponding massless Green functions. They satisfy homogeneous equations:

Similar relations may be derived for 1,r) and the coherence of our assumption checked if the solution is negligible with respect to pn). The solution ofEqs. (13-82) will exhibit a structure reminiscent of the relation between bare and renormalized theory. The reason lies clearly in the way the equations were obtained. The difference will be that infinities are no longer involved. A finite renormalization effect will accompany a change of momentum scale. To describe it let g(A) be the solution of the differential equation

Equation (13-82) takes the form A :A {A 4 - nZ(A)-n r'\;)[A- 1 Pi;g(A)]} = 0 meaning that (13-86) The departure from the naive scaling factor A4 - n arises as an anomalous dimension [Z(A)-n] and a change in the coupling constant g(A). It remains to find what happens in the limit A -+ 00. In particular, we have to study the limiting behavior of g(A). From Eq. (13-83) it is clear that the crucial issue is the location of the zeros of fJ(g). It may occur exceptionally that the initial coupling g(l) just coincides with such a zero, call it goo. In this case g(A) = goo independently of A. In general, g(A) will vary as A -+ 00 ; it grows if fJ is positive or decreases if fJ < O. This variation is only interrupted when it meets a zero of fJ. A possible situation is an evasion of g at infinity when A grows. This would happen if fJ is of the same sign as g for all g, and vanishes only at the origin. Such a strong coupling situation is hard to analyze. In order that g(A) tends to a finite limit goo as A -+ 00 it is necessary that fJ(goo) vanishes and that (g - goo)fJ(g) be negative in the neighborhood of goo. This is called an ultraviolet fixed point (Fig. 13-5). It could happen that a fixed point is ultraviolet attractive on one side and ultraviolet repulsive on the other. Such is the case if two simple zeros coalesce. For a simple attractive zero In A will diverge as In A ~ (13-85)
