Abstract: (APS)
We calculate the O(ε2) terms of the Wilson expansion of the critical exponents in the Reggeon field theory with a bare linear trajectory and a triple-Regge interaction. We find that the O(ε2) and O(ε) terms are comparable at ε=2, and we obtain σtot(S)S→∞∼(lns)0.38. We also show that the Gell-Mann-Low function β(g) expanded to finite order in both ε and g carries no information about the existence of the Gell-Mann-Low zero at finite ε.- RENORMALIZATION GROUP: CALLAN-SYMANZIK EQUATION
