The production of D∗± mesons in deep inelastic ep scattering has been mea- sured for exchanged photon virtualities 5 < Q2 < 1000 GeV2, using an integrated luminos- ity 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, σcc ̄ .

Abstract
The production of D∗± mesons in deep inelastic ep scattering has been mea- sured for exchanged photon virtualities 5 < Q2 < 1000 GeV2, using an integrated luminos- ity 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, σcc ̄ . Theoretical calculations based on fits to red inclusive HERA data are compared to the results.File in questo prodotto:
