Probing the supersymmetric O(N) σ model to O(1/N2): Critical exponent ν
Description
We present a detailed evaluation of the critical exponent ν at O(1/N2) in the supersymmetric σ model on SN, which shows that the coefficients of the perturbative β-function at four and higher loop are purely transcendental numbers. Consequently, the anomalous dimension γ(g), is given to the same large-N approximation. (orig.)
