Abstract
Production of final states containing open charm (c) and beauty (b) 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 compared to QCD predictions. The excited charm mesons D-1(0)(2420), D-2*(0)(2460) and D-s1(+/-) (2536) have been observed and the rates of charm quarks hadronising to these mesons were extracted. A search for radially excited charm mesons has been performed. PHP and DIS beauty cross sections are higher than expected in next-to-leading order (NLO) QCD.
