Parton distribution functions (PDFs) are an invaluable tool for particle physicists. But, they can be tricky to work with, and there is a growing need to develop new software to help these functions.
The team summarize the need for such a program in their recent LabTalk article in JPhysG:
The requirements of precision physics at CERN’s Large Hadron Collider (LHC) have lead to the development of a variety of computer programs that can be used to analyze LHC data and to provide predictions for phenomenologically relevant processes. Following the technical developments of such programs we noticed the lack of programs for the visualization and manipulation of parton distribution functions (PDFs) which are one of the most important ingredients when computing predictions for modern colliders.
The new app will help researchers across the globe to work with PDFs, and the team believe it has the potential to become a highly used tool for LHC researchers over the coming years.
