Abstract

We establish the existence of the Wilson Renormalised trajectory of the O(N) sigma model in perturbation theory in the "effective charge". This yields a proof of perturbative renormalisability, and is also relevant in the "small-field" analysis of the rigorous renormalisation group construction of the continuum theory.
