- Abstract
We analyze the contribution from excitation of the (qq)( ff), (qq)g1...gn( ff) Fock states of a photon to high-mass diffraction in DIS. We show that the large-Q2 behavior of this contribution can be described by DLLA evolution from the nonperturbative ff valence state of the pomeron. Although of higher order in pQCD, the new contribution to high-mass diffraction is comparable to that from the excitation of the qqg Fock state of the photon. © 2004 MAIK “Nauka / Interperiodica”.
