Query: Next-to-leading order evolution of twist-two conformal operators: The
  abelian case   We present the method, based on the use of the broken conformal Ward
identities, for the calculation of the anomalous dimensions of conformal
operators beyond the leading order of perturbation theory. By means of this
technique we find the complete set of two-loop corrections to the off-diagonal
elements of the anomalous dimension matrix (the diagonal ones are known from
deep inelastic scattering calculations) of the parity odd and even singlet
local operators in the Abelian gauge theory. We reconstruct corresponding
exclusive two-loop evolution kernels and give the reduction formulae for the
restoration of the diagonal part of the ER-BL kernels from the DGLAP splitting
functions.
