K-factorization

I review the k-factorization method to combine the high-energy behaviour in QCD with the renormalization group. Resummation formulas for coefficient functions and anomalous dimensions are derived, and their applications to small-x scaling violations in structure functions are briefly discussed.I review the k-factorization method to combine the high-energy behaviour in QCD with the renormalization group.
