Evolution kernels of skewed parton distributions: method and two-loop results
A. V. Belitsky, A. Freund, D. Müller
We present a formalism and explicit results for two-loop flavor singlet evolution kernels of skewed parton distributions in the minimal subtraction scheme. This approach avoids exp…
Deeply virtual Compton scattering in next-to-leading order
A. V. Belitsky, D. Müller, L. Niedermeier +1
We study the amplitude of deeply virtual Compton scattering in next-to-leading order of perturbation theory including the two-loop evolution effects for different sets of skewed pa…
Exclusive evolution kernels in two-loop order: parity even sector
A. V. Belitsky, D. Müller
We complete the construction of the non-forward evolution kernels in next-to-leading order responsible for the scale dependence of e.g. parity even singlet distribution amplitudes.…
Scaling violations and off-forward parton distributions: leading order and beyond
A. V. Belitsky, D. Muller
We give an outline of a formalism for the solution of the evolution equations for off-forward parton distributions in leading and next-to-leading orders based on partial conformal…
$\cN = 1$ supersymmetric constraints for evolution kernels
A. V. Belitsky, D. Müller
We provide a complete set of supersymmetric constraints for the anomalous dimensions of the conformal twist-two operators to all orders of perturbation theory. Employing them we de…
Reconstruction of non-forward evolution kernels
A. V. Belitsky, D. Müller, A. Freund
We develop a framework for the reconstruction of the non-forward kernels which govern the evolution of twist-two distribution amplitudes and off-forward parton distributions beyond…
