Abstract :
Using operator product expansions and a graphical ansatz for the four-point function of the fundamental field φa(x) in the conformally invariant O(N) vector model, we calculate the next-to-leading order in 1N values of the quantities CT and CJ. We check the results against what is expected from possible generalisations of the C- and k-theorems in higher dimensions and also against known three-loop calculations in a O(N) invariant teta;4 theory for d = 4 − ϵ.
