For generic values of N, and in particular for the physically interesting cases N=0,1,2,3, we determine the six-point and eight-point renormalized coupling constants which parametrize its small-field expansion. These estimates are obtained from the analysis of their $\\epsilon$-expansion, taking into account the exact results in one and zero dimensions, and, for the Ising model (i.e. N=1), the accurate high-temperature estimates in two dimensions. They are compared with the available results from other approaches. We also obtain corresponding estimates for the two-dimensional O($N$) models.", "revisions": [ { "version": "v1", "updated": "1998-01-12T12:48:48.000Z" } ], "analyses": { "subjects": [ "05.70.Jk", "64.60.Fr", "05.50.+q", "75.10.Hk", "11.10.Kk", "11.15.Tk" ], "keywords": [ "effective potential", "accurate high-temperature estimates", "generic values", "three-dimensional models", "zero dimensions" ], "tags": [ "journal article" ], "publication": { "publisher": "Elsevier", "journal": "Nucl.
