摘要：

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(x(1),x(2),t,mu(2)) can be well approximated at small x by the conventional gluon density xG(x,mu(2)). (C) 1998 Elsevier Science B.V.
