Abstract
We develop the pQCD description of diffraction excitation of heavy fla vours in DIS and we derive the analytic formulas for the mass spectrum in leading log m(f)(2). The result illustrates nicely the non-factori zation properties of the QCD pomeron. We predict a very steep rise of the charm content of diffraction dissociation of photons at small x(p) . We evaluate the contribution of open charm to scaling violations in the structure function of the pomeron.
