- Аннотация: Deep inelastic scattering and its diffractive component, , have been studied at HERA with the ZEUS detector using an integrated luminosity of 52.4 pb−1. The method has been used to extract the diffractive contribution. A wide range in the centre-of-mass energy W (37–245 GeV), photon virtuality (20–450 GeV2) and mass (0.28–35 GeV) is covered. The diffractive cross section for rises strongly with W, the rise becoming steeper as increases. The data are also presented in terms of the diffractive structure function, , of the proton. For fixed and fixed , shows a strong rise as , where is the fraction of the proton momentum carried by the pomeron. For Bjorken-, shows positive scaling violations, while for negative scaling violations are observed. The diffractive structure function is compatible with being leading twist. The data show that Regge factorisation is broken.
