Résumé

A measurement is presented of the cross section for D*± meson production in diffractive deep-inelastic scattering for the first time at HERA. The cross section is given for the process ep → eXY, where the system X contains at least one D*± meson and is separated by a large rapidity gap from a low mass proton remnant system Y. The cross section is presented in the diffractive deep-inelastic region defined by 2 < Q2 < 100 GeV2, 0.05 < y < 0.7, x < 0.04, MY < 1.6 GeV and |t| < 1 GeV2. The D*± mesons are restricted to the range pT,D* > 2 GeV and |ηD*| < 1.5. The cross section is found tobe 246±54±56 pb and forms about 6% of the corresponding inclusive D*± cross section. The cross section is presented as a function of various kinematic variables, including zobs which is an estimate of the fraction of the momentum of the diffractive exchange carried by the parton entering the hard-subprocess. The data show a large component of the cross section at low zobs where the contribution of the boson-gluon-fusion process is expected to dominate. The data are compared with several QCD-based calculations.
