摘要：

Starting from a four-gluon partial-wave amplitude which provides the first unitarity corrections to the Lipatov Pomeron we study the deep inelastic limit. We find mixing between the four-gluon operator and a twist-four piece of the two-gluon operator. We calculate the diagonal elements of the matrix of the anomalous dimensions and the coefficient function of the singular part (near n = 1) of the four-gluon operator. Several disagreements between our results and the Gribov-Levin-Ryskin evolution equation are found.
