Measurement of the open-charm contribution to the diffractive proton structure function

Production of D*±(2010) mesons in diffractive deep inelastic scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 82 pb-1. Diffractive events were identified by the presence of a large rapidity gap in the final state. Differential cross sections have been mea...

Description
Summary:Production of D*±(2010) mesons in diffractive deep inelastic scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 82 pb-1. Diffractive events were identified by the presence of a large rapidity gap in the final state. Differential cross sections have been measured in the kinematic region 1.5<q2<200 0.02<y<0.7,="" gev2,="" pt(d*±)="" xp<0.035,="" β<0.8,="">1.5 GeV and η(D*±) &lt;1.5. The measured cross sections are compared to theoretical predictions. The results are presented in terms of the open-charm contribution to the diffractive proton structure function. The data demonstrate a strong sensitivity to the diffractive parton densities. © 2003 Published by Elsevier B.V.</q2<200>
