Including heavy quark production in ZEUS-PDF fits
At HERA heavy quarks may contribute up to 30% of the structure function F2. The potential of including heavy-quark data in the ZEUS PDF fits is explored, using D* double dierential cross-sections as well as the inclusive quantities Fcc2 , Fcc2 .

| Summary: | At HERA heavy quarks may contribute up to 30% of the structure function F2. The potential of including heavy-quark data in the ZEUS PDF fits is explored, using D* double dierential cross-sections as well as the inclusive quantities Fcc2 , Fcc2 . The introduction of heavy quarks requires an extension of the DGLAP formalism. The effect of using different heavy avour number schemes, and different approaches to the running of αs, are compared. |
