We compute the four-loop contributions to the beta-function and the anomalous dimension of the field for the O(N)-invariant N-vector model. These results are used to compute the second analytic corrections to the correlation length and the general spin-n susceptibility.

Abstract
We compute the four-loop contributions to the beta-function and the anomalous dimension of the field for the O(N)-invariant N-vector model. These results are used to compute the second analytic corrections to the correlation length and the general spin-n susceptibility.File allegati a questo prodotto
