Measurement of D* production in diffractive deep inelastic scattering at HERA

Popis výsledku v původním jazyce

Measurements of D∗ (2010) meson production in diffractive deep inelastic scattering (5<Q**2 <100 GeV**2 ) are presented which are based on HERA data recorded at a centre-of-mass energy √s = 319 GeV with an integrated luminosity of 287 pb**−1 . The reaction ep→eXY is studied, 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 measured cross sections compare favourably with next-to-leading order QCD predictions, where charm quarks are produced via boson-gluon fusion. The charm quarks are then independently fragmented to the D∗ mesons. The calculations rely on the collinear factorisation theorem and are based on diffractive parton densities previously obtained by H1 from fits to inclusive diffractive cross sections. The data are further used to determine the diffractive to inclusive D∗ production ratio in deep inelastic scattering
