N2 - xFitter [1] is an open-source package that provides a framework for the determination of the parton distribution functions (PDFs) of the proton for many different kinds of analyses in Quantum Chromodynamics (QCD). It incorporates experimental data from a wide range of experiments including fixed-target, Tevatron, HERA, and LHC. xFitter version 2.0.0 has recently been released, and offers an expanded set of tools and options. The new xFitter 2.0.0 program links to the APFEL code [2] which has implemented generalized matching conditions that enable the switch from NF to NF +1 active flavors at an arbitrary matching scale μm. This enables us to generalize the transition between a FFNS and a VFNS and essentially vary continuously between the two schemes; in this sense the matching scale μm allows us to unify the FFNS and VFNS in a common framework [3]. This paper provides a brief overview of xFitter with emphasis of these new features.
