Description
Exclusive charm vector meson production has been studied in the high
statistics HERA-2 data.
H1 has measured the elastic and proton-dissociative photoproduction
cross sections of J/psi mesons as function of W_{gamma p} and t. The
W_{gamma p} and t dependencies are parametrised using phenomenological
fits, and results are compared to other measurements.
ZEUS has measured the cross section ratio of exclusive DIS production of
psi(2S) to psi(1S) as function of Q^2, W_{gamma p} and t.
