We determine the crossover exponents associated with the traceless tensorial quadratic field and the third- and fourth-harmonic operators for O(n) vector models by reanalyzing the existing six-loop fixed-dimension series with the pseudo-epsilon expansion.

Abstract

We determine the crossover exponents associated with the traceless tensorial quadratic field and the third- and fourth-harmonic operators for O(n) vector models by reanalyzing the existing six-loop fixed-dimension series with the pseudo-epsilon expansion. With this approach we obtain accurate theoretical estimates that are in optimum agreement with other theoretical and experimental results.
