Including heavy quark production in ZEUS-PDF fits

High Energy Physics - Phenomenology 2008-08-14 v1

Abstract

At HERA heavy quarks may contribute up to 30% of the structure function F2F_2. The potential of including heavy-quark data in the ZEUS PDF fits is explored, using DD^* double differential cross-sections as well as the inclusive quantities F2ccˉF_2^{c\bar{c}}, F2ccˉF_2^{c\bar{c}}. The introduction of heavy quarks requires an extension of the DGLAP formalism. The effect of using different heavy flavour number schemes, and different approaches to the running of αs\alpha_s, are compared.
