Abstract

The longitudinal and transverse components of the cross section for the ep → e′ pρ⁰ reaction were measured in Hall B at Jefferson Laboratory using the CLAS detector. The data were taken with a 4.247 GeV electron beam and were analyzed in a range of ^xB from 0.2 to 0.6 and of Q² from 1.5 to 3.0 GeV2. The data are compared to a Regge model based on effective hadronic degrees of freedom and to a calculation based on Generalized Parton Distributions. It is found that, at our lowest ^xB values, the transverse part of the cross section is well described by the former approach while the longitudinal part can be reproduced by the latter.
