Abstract

We develop the pQCD description of diffraction excitation of heavy flavours in DIS and we derive the analytic formulas for the mass spectrum in leading logmf2m_f^{2}. The result illustrates nicely non-factorization properties of the QCD pomeron. We predict a very steep rise of the charm content of diffraction dissociation of photons at small x\Pomx_{\Pom}. We evaluate the contribution of open charm to scaling violations in the structure function of the pomeron.
