Abstract

We analyze the contribution from excitation of the \((q\bar q)(f\bar f), (q\bar q)g_1 \cdots g_n (f\bar f)\) 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 \(f\bar f\) 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 \(q\bar qg\) Fock state of the photon.
