摘要
We discuss the calculation of the evolution kernels Delta W-zeta(X,Z) for the leading-twist nonforward parton distributions G(zeta)(X,t) sensitive to parton helicities. We present our results for the kernels governing evolution of the relevant light-ray operators and describe a simple method allowing to obtain from them the components of the nonforward kernels Delta W-zeta(X,Z).
