摘要

We report on a completely analytical calculation of the field anomalous dimension gamma(phi) and the critical exponent eta for the O(n)-symmetric phi(4) model at the record six loop level. We successfully compare our result for gamma(phi) with n = 1 with the predictions based on the method of the Borel resummation combined with a conformal mapping (Kazakov et al., 1979 [40]). Predictions for seven loop contribution to the field anomalous dimensions are given. (C) 2016 The Authors. Published by Elsevier B.V.
