ABSTRACT

Exclusive ρ0 electroproduction at HERA has been studied with the ZEUS detector using 120 pb-1 of integrated luminosity collected during 1996–2000. The analysis was carried out in the kinematic range of photon virtuality 2 the Q2 and W dependence of the γ*p → ρ0p cross section and the distribution of the squared-four-momentum transfer to the proton. The helicity analysis of the decay-matrix elements of the ρ0 was used to study the ratio of the γ*p cross section for longitudinal and transverse photon as a function of Q2 and W. Finally, an effective Pomeron trajectory was extracted. The results are compared to various theoretical predictions.PACS Codes: 13.60.Hb, 13.60.Le More... »
