| Abstract | Measurements of open charm production are presented in diffractive deep inelastic scattering (5<Q2<100 GeV2), based on HERA data recorded at sqrt(s) = 318 GeV with an integrated luminosity of 281 pb-1. The event topology is given by ep→eXY, where the system X, containing at least one D*(2010) meson, is separated from a leading low-mass proton dissociative system Y by a large rapidity gap. The D* candidates are reconstructed fully in the D*+→D0π+→(K-π+)π+ (+C.C.) decay channel. The measured differential cross sections are compared at the level of stable hadrons with next-to-leading order QCD predictions obtained in the massive scheme, where the charm quark is produced via the boson-gluon fusion, using diffractive parton densities previously obtained by H1 from fits of the inclusive diffractive cross sections. |
