Abstract:
Deep inelastic scattering and its diffractive component, ep→e′γ*p→e′XN, have been studied at HERA with the ZEUS detector using an integrated luminosity of 52.4 pb−1. The MX method has been used to extract the diffractive contribution. A wide range in the centre-of-mass energy W (37–245 GeV), photon virtuality Q2 (20–450 GeV2) and mass MX (0.28–35 GeV) is covered. The diffractive cross section for 20, where xIP is the fraction of the proton momentum carried by the pomeron. For Bjorken-x<1×10−3, xIPF2D(3) shows positive logQ2 scaling violations, while for x >= 5×10−3 negative scaling violations are observed. The diffractive structure function is compatible with being leading twist. The data show that Regge factorisation is broken.
