Measurements of open charm and beauty production cross sections in ep deep inelastic scattering (DIS) at HERA from the H1 and ZEUS collaborations are combined. Reduced cross sections are obtained in a restricted kinematic range. Perturbative QCD calc

Charm production at HERA from the 1994 data samples of the H1 and ZEUS experiments with luminosities of ≈ 3 pb −1 each has been observed, where 27.5 GeV positrons collided with 820 GeV protons. Results are presented on elastic J / ψ in photoprod

Inclusive charm meson production cross sections in the deep inelastic scattering and photoproduction regimes are compared with QCD leading and next-to-leading (NLO) calculations. The NLO predictions are significantly below the data in some parts of t

Production of final states containing open charm and beauty quarks at HERA is reviewed. Photoproduction (PHP) of the charm meson resonances D^*, D^0 and D_s, as well as D^* production in the deep inelastic scattering (DIS) regime, are measured and co

We have observed, in a high-statistics experiment, well-defined threshold enhancements in the ${\ensuremath{\rho}}^{0}{\ensuremath{\pi}}^{\ensuremath{-}}$ and ${f}^{0}{\ensuremath{\pi}}^{\ensuremath{-}}$ systems at 1120 and 1645 MeV, respectively. We
