Measurement of the D∗±D∗± meson production cross section and F2cc¯ at high Q2Q2 in ep scattering at HERA


H1 Collaboration; et al; Aaron, F D; Alexa, C; Baghdasaryan, A; Barrelet, E; Bartel, W; Begzsuren, K (2010). Measurement of the D∗±D∗± meson production cross section and F2cc¯ at high Q2Q2 in ep scattering at HERA. Physics Letters B, 686(2-3):91-100.

Abstract

The inclusive production of D*±(2010) mesons in deep-inelastic e±p scattering is measured in the kinematic region of photon virtuality 100<Q2<1000 GeV2 and inelasticity 0.02<y<0.7. Single and double differential cross sections for inclusive D* meson production are measured in the visible range defined by |η(D*)|<1.5 and pT(D*)>1.5 GeV. The data were collected by the H1 experiment during the period from 2004 to 2007 and correspond to an integrated luminosity of 351 pb−1. The charm contribution, View the MathML source, to the proton structure function F2 is determined. The measurements are compared with QCD predictions.
