D^{+}, D^{0} and Lambda_{c}^{+} production in deep inelastic scattering at HERA

Abstract

Several recent measurements of charmed hadron production in deep inelastic scattering at HERA are reviewed. Cross sections for the production of D mesons were measured and compared to NLO QCD predictions. The charm contribution to the inclusive structure function F_{2} was extracted and compared to previous measurements and theoretical predictions. The reconstruction of decays with a neutral strange hadron in the final state allowed the measurement of charm production to be extended into the low transverse momentum region. The fraction of c quarks hadronising into Lambda_{c}^{+} baryons was extracted using two different decay modes.
