Abstract
We study the possibility of an ultraviolet (UV) zero in the six-loop beta function of an O(N) λ|φ→|4 field theory in d=4 spacetime dimensions. For general N, in the range of values of λ where a perturbative calculation is reliable, we find evidence against such a UV zero in this six-loop beta function.
