Phys. Rev. D 56, 3007–3010 (1997)Diffractive electroproduction of ρ meson excitationsReceived 20 January 1997; published in the issue dated 1 September 1997 We use perturbative QCD and parton-hadron duality to estimate the cross sections for the diffractive electroproduction of ρ′(1-) and ρ(3-) resonances which occur in the 1.3–1.8 GeV mass interval. We present the cross sections and the ratios σL/σT as a function of Q2. We compare the predictions with those for the diffractive electroproduction of ρ mesons. We show how such diffractive electroproduction measurements at DESY HERA can probe features of the perturbative QCD “Pomeron.” © 1997 The American Physical Society URL:
