摘要：

I consider the next-to-leading high-energy cluster expansion of large-k double jet production in QCD, and I determine the corresponding one-loop quark and gluon impact factors for a self-consistent energy scale. The result shows that coherent angular ordering of emitted gluons holds for hard emission also, and singles out a scale which in essentially the largest virtuality in the process. Both remarks are relevant for the precise determination of the BFKL kernel at the next-to-leading level. (C) 1998 Elsevier Science B.V. All rights reserved.
