Abstract

In this paper we make predictions for nondiagonal parton distributions in a proton in the LLA. We calculate the DGLAP-type evolution kernels in the LLA, solve the nondiagonal GLAP evolution equations with a modified version of the CTEQ-package and comment on the range of applicability of the LLA in the asymmetric regime. We show that the nondiagonal gluon distribution g(x1,x2,t,μ2)g(x_{1},x_{2},t,\mu^2) can be well approximated at small xx by the conventional gluon density xG(x,μ2)xG(x,\mu^2).
