Abstract
We analyze the contribution from excitation of
the
Fock states
of the photon to high mass diffraction in DIS.
We show that the large Q2 behavior of this contribution can be described
by the DLLA evolution from the non-perturbative 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 Fock state of the
photon.
