Intrinsic $k_{\perp}$ in the pomeron

High Energy Physics - Phenomenology 2007-05-23 v2

Abstract

In a consistent QCD approach to diffractive DIS gluons in the pomeron have soft zgz_{g} distribution and very broad intrinsic kk_{\perp} distribution. The latter has not yet been incorporated into diffractive Monte-Carlo generators (RAPGAP,....). I argue that the so-introduced bias in the diffractive jet analysis may be the reason why H1 Collaboration finds the very large and hard gluon content of the pomeron. I discuss possible direct experimental determinations of intrinsic kk_{\perp} in the pomeron.
