摘要：
Four new measurements are presented in the area of diffractive and exclusive production at HERA. Preliminary results are available for isolated photons in diffractive photoproduction from ZEUS and open charm cross section in diffractive deep-inelastic scattering (DIS) regime from H1. ZEUS Collaboration has also measured the cross-section ratio sigma(psi(2S))/sigma(J/psi(1S)) in exclusive DIS using full HERA data statistics. Finally, H1 Collaboration for the first time studied exclusive rho(0) meson photoproduction associated with a leading neutron at HERA.
