Description
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 MSbar 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.
The scale dependence of the mass is found to be consistent with QCD
expectations.
