Contribution

It provides new measurements of D meson cross sections, charm contribution to F2, and Lambda_c+ production, enhancing understanding of charm production mechanisms at HERA.

Findings

D meson cross sections agree with NLO QCD predictions

Charm contribution to F2 matches previous measurements and models

Extended charm production measurements into low transverse momentum region

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.
