Abstract

H1 and ZEUS have published single-differential cross sections for inclusive D*(+/-)-meson production in deep-inelastic ep scattering at HERA from their respective final data sets. These cross sections are combined in the common visible phase-space region of photon virtuality Q(2) > 5 GeV2, electron inelasticity 0.02 < y < 0.7 and the D*(+/-) meson's transverse momentum p(T)(D*) > 1.5 GeV and pseudorapidity vertical bar eta(D*)vertical bar < 1.5. The combination procedure takes into account all correlations, yielding significantly reduced experimental uncertainties. Double-differential cross sections d(2)sigma/dQ(2)dy are combined with earlier D*(+/-) data, extending the kinematic range down to Q(2) > 1.5 GeV2. Perturbative next-to-leading-order QCD predictions are compared to the results. |
