Measurement of D*± production in deep inelastic scattering at HERA

The production of D * ± mesons in deep inelastic ep scattering has been measured for exchanged photon virtualities 5 2 2 , using an integrated luminosity of 363 pb -1 with the ZEUS detector at HERA. Differential cross sections have been measured and compared to next-to-leading-order QCD calculations. The cross-sections are used to extract the charm contribution to the proton structure functions, expressed in terms of the reduced charm cross section, σ red cc . Theoretical calculations based on fits to inclusive HERA data are compared to the results. © 2013 SISSA.
