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 can be well approximated at small by the conventional gluon density . Keywords: Hard Diffractive Scattering, Nondiagonal distributions, Evolution
