Description
In this talk I will present a novel determination of the mass of the
charm quark extracted by analyzing the statistical quality of fits of
parton distribution functions (PDFs) to inclusive and exclusive charm
deep-inelastic scattering (DIS) cross-section data from Runs I and II
of the HERA collider. We employ the running mass definition in the
MSbar scheme, which improves the perturbative stability as compared to
the pole-mass definition, in the framework of the FONLL general-mass
scheme. The analysis is based on the xFfitter framework, with
structure functions computed in the FONLL scheme as implemented in the
APFEL code.
