Abstract
We calculate the cross section for
-production in
diffractive DIS with finite quark masses at zero momentum transfer
t.
The calculation is done in the leading log(1/
)
and is valid in the region of high diffractive masses
M
(small
). We apply our cross section formula including
both
- and
in a Monte Carlo simulation to diffractive
meson
production at HERA.
We compare our predictions to results of H1
using three parameterizations for the unintegrated gluon density.
