Abstract

An overview of recent measurements of charm and beauty production in ep collisions at HERA is presented. Various techniques are used by the ZEUS and H1 collaborations to efficiently tag heavy quarks in events and different regions of phase space are explored. Differential cross sections are measured in both photoproduction and deep-inelastic scattering. The predictions based on perturbative QCD calculations at next-to-leading order are generally found to describe the proton structure and the production of heavy quarks.
