    Description
    The powerful techniques of asymptotic operation allow one to obtain an all-orders factorization theorem for the large-s behaviour of total cross sections. The upshot is that predicting large-s evolution is impossible without non-trivial hypotheses about small-x behaviour of parton distributions. A by-product is a systematic formalism for NNLO calculations of the standard QCD evolution kernels.
