Description
We present the xFitter project (former HERAFitter) which provides a unique open-source software framework for the determination of the proton's PDFs and for the interpretation of the physics analyses in the context of Quantum Chromodynamics.
We highlight the new xFitter software release which includes many new
features and additions, e.g. the possibility of the inclusion of photon PDF,
updated variable and fixed-flavour schemes for heavy quarks, interface to
the APFEL library and n-space evolution program MELA, updates to the
latest theory calculations and many more.
We will also report on the latest xFitter results on the new determination of
the mass of the charm quark extracted by analysing the statistical quality of
fits to inclusive and exclusive charm deep-inelastic scattering data from
the HERA collider.
