Five-loop renormalization-group expansions for two-dimensional Euclidean λφ theory

Abstract

The renormalization-group functions of the two-dimensional nvector λφ4 model are calculated in the five-loop approximation. Perturbative series for the β-function and critical exponents are resummed by the Pade-Borel-Leroy techniques. An account for the five-loop term shifts the Wilson fixed point location only briefly, leaving it outside the segment formed… (More)
