Description

We present the HERAFitter project, a unique platform for QCD analyses of hadron-induced processes in the context of multi-process and multi-experiment setting. Based on the factorisable nature of the hadronic cross sections into universal parton distribution functions (PDFs) and process dependent partonic scattering cross sections, HERAFitter allows determination of the PDFs from various hard scattering measurements. The project successfully encapsulates a wide variety of QCD tools to facilitate investigations of the experimental data and theoretical calculations. HERAFitter is the first open source platform which is optimal for benchmarking studies. It allows for direct comparisons of various theoretical approaches under the same settings, a variety of different methodologies in treating of the experimental and model uncertainties. The growth of HERAFitter benefits from its flexible modular structure driven by QCD advances.
