Four-Loop Perturbative Expansion for the Lattice N-Vector Model
Abstract
We compute the four-loop contributions to the β-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.
