Title: Running of the charm-quark mass from HERA deep-inelastic scattering data

Combined HERA data on charm production in deep-inelastic scattering have previously been used to determine the charm-quark running mass m c(m c) in the MS¯ renormalisation scheme. Here, the same data are used as a function of the photon virtuality Q 2 to evaluate the charm-quark running mass at different scales to one-loop order, in the context of a next-to-leading order QCD analysis. Lastly, the scale dependence of the mass is found to be consistent with QCD expectations.
