Abstract:
Exclusive electroproduction of mesons has been studied in collisions at \sqrt{s}=318 \gev with the ZEUS detector at HERA using an integrated luminosity of 65.1 pb. The cross section is presented in the kinematic range 2, and helicity angle are compared to cross sections for other vector mesons. The ratios of the cross sections for longitudinally and transversely polarized virtual photons are presented as functions of and . The data are also compared to predictions from theoretical models.,
