HERAFitter, Open Source QCD Fit Project

Alekhin, S., Behnke, O., Belov, P. et al.

Understand

HERAFitter is an open-source package that provides a framework for the determination of the parton distribution functions (PDFs) of the proton and for many different kinds of analyses in Quantum Chromodynamics (QCD).

  • It encodes results from a wide range of experimental measurements in lepton-proton deep inelastic scattering and proton-proton (proton-antiproton) collisions at hadron colliders.
  • These are complemented with a variety of theoretical options for calculating PDF-dependent cross section predictions corresponding to the measurements.
  • The framework covers a large number of the existing methods and schemes used for PDF determination.
