The formula is valid for all conformal spin configurations of the quark-antiquark and gluon-gluon states. In particular, a new selection rule on conformal spins characterizes the non-dominant BFKL components with intercept below the Pomeron in the conformal-invariant framework.12 pages, latex with tcilatex, no figureHigh Energy Physics - PhenomenologyHigh Energy Physics - Theorytext
