Five-loop critical exponents of the weakly diluted Ising model: 3D approach versus √ε-expansion
R. Folk, Yurij V. Holovatch, Taras Yavors’kii
Based on the recently obtained ve{loop renormalization group functions of the 4 {theory with O(n){symmetric and cubic interactions, we analyse these functions for the weakly diluted Ising model case n = 0 both by means of the p "{expansion and in the xed d = 3 technique.We apply dierent resummation procedures and report numerical values for the critical exponents dependent on the order of approximation.We compare the convergence of the results obtained in the framework of the two schemes.
