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.
