Abstract:

Exclusive production of

\rho^0

and

J/\psi

mesons in e^+ p collisions has been studied with the ZEUS detector in the kinematic range

0.25 < Q^2 < 50 GeV^2, 20 < W < 167 GeV

for the

\rho^0

data and

2 < Q^2 < 40 GeV^2, 50 < W < 150 GeV

for the

J/\psi

data. Cross sections for exclusive

\rho^0

and

J/\psi

production have been measured as a function of

Q^2, W

and

t

. The spin-density matrix elements

r^{04}_{00}, r^1_{1-1}

and

Re r^{5}_{10}

have been determined for exclusive

\rho^0

production as well as

r^{04}_{00}

and

r^{04}_{1-1}

for exclusive

J/\psi

production. The results are discussed in the context of theoretical models invoking soft and hard phenomena.
