Abstract

AT HERA heavy quarks may contribute up to 30% of the structure function F₂. 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 α_s, are compared using the ZEUS PDF fit formalism. The potential of including charm data in the fit is explored, using D^* double differential cross-sections rather than the inclusive quantity F₂^cc.
