Abstract: | We calculate the effect of the less singular terms at small x on the evolution of the coefficient function in φ3 theory in six dimensions, which result from a complete solution of the ladder equation. Scale-invariant next-to-leading order contributions are also studied. We show that the small-x approximation does not deliver the dominant contributions. |
