Abstract
Exclusive production of ρ0 and J/ψ mesons in e+p collisions has been studied with the ZEUS detector in the kinematic range 0.25 < Q2 < 50 GeV2, 20 < W < 167 GeV for the ρ0 data and 2 < Q2 < 40 GeV2, 50 < W < 150 GeV for the J/ψ data. Cross sections for exclusive ρ0 and J/ψ production have been measured as a function of Q2, W and t. The spin-density matrix elements r0400, r11-1i and Re r510 have been determined for exclusive ρ0 production as well as r0400 and r041-1 for exclusive J/ψ production. The results are discussed in the context of theoretical models invoking soft and hard phenomena.
