We claim that factorization implies that the evolution kernel, defined by the logarithmic derivative of the Nth moment of the structure function d In F-2(N) /d in Q(2), receives logarithmically enhanced contributions (Sudakov logs) from a single source, namely, the constrained invariant mass of the jet. Available results from fixed-order calculations facilitate Sudakov resummation up to the next-to-next-to-leading logarithmic accuracy. We use additional all-order information on the physical kernel from the large-beta(0) limit to model the behaviour of further subleading logs and explore the uncertainty in extracting alpha(s) and in determining the magnitude of higher-twist contributions from a comparison with data on high moments.
