Abstract.

We calculate the cross section for \(c\bar cg\)-production in diffractive DIS with finite quark masses at zero momentum transfer t. The calculation is done in the leading log(1/\(x_{\mathbb{P}}\)) approximation and is valid in the region of high diffractive masses M (small \(\beta\)). We apply our cross section formula including both \(c{\bar c}\)- and \(c\bar cg\) in a Monte Carlo simulation to diffractive \(D^{*\pm}\) meson production at HERA. We compare our predictions to results of H1 using three parameterizations for the unintegrated gluon density.
