Abstract
It is shown that the next-to-leading order (NLO) corrections to the QCD Pom eron intercept obtained from the Balitsky-Fadin-Kuraev-Lipatov (BFKL) equat ion, when evaluated in non-Abelian physical renormalization schemes with Br odsky-Lepage-Mackenzie (BLM) optimal scale setting, do not exhibit the seri ous problems encountered in the <(MS)over bar> scheme. A striking feature o f the NLO BFKL Pomeron intercept in the BLM approach is that it yields an i mportant approximate conformal invariance. (C) 1999 American Institute of P hysics.
