NLO Exclusive Evolution Kernels
  We outline a formalism used for a construction of two-loop flavor singlet exclusive evolution kernels in the MS bar scheme. The approach is based on the known pattern of conformal symmetry breaking in MS bar as well as constraints arising from the superconformal algebra of the N = 1 super Yang-Mills theory.
