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