Five-loop renormalization-group expansions for the three-dimensional n-vector cubic model and critical exponents for impure Ising systems

The renormalization-group (RG) functions for the three-dimensional n-vector cubic model are calculated in the five-loop approximation. High-precision numerical estimates for the asymptotic critical exponents of the three-dimensional impure Ising systems are extracted from the Eve-loop RG series by means of the Pade-Borel-Leroy resummation under n=0. These exponents are found to he gamma=1.325+/-0.003, eta=0.025+/-0.01, nu=0.67+/-0.005, alpha=-0.0125+/-0.008, and beta=0.344+/-0.006. For the correction-to-scaling exponent, the less accurate estimate omega=0.32+/-0.06 is obtained.
