摘要：
We determine an approximate expression for the O(alpha(3)(S)) contribution chi(2) to the kernel of the BFKL equation, which includes all collinear and anticollinear singular contributions. This is derived using recent results on the relation between the GLAP and BFKL kernels (including running-coupling effects to all orders) and on small-x factorization schemes. We present the result in various schemes, relevant both for applications to the BFKL equation and to small-x evolution of parton distributions. (c) 2007 Elsevier B.V. All rights reserved.
