Global QCD Analyses

An on-going comprehensive global QCD analysis project to test the accuracy of QCD and to extract the universal parton distribution functions needed in calculations of all high energy physics processes

CTEQ Tools

• ManeParse version 1.0 ManeParse is a modular Mathematica package that provides access to PDFs for hadronic calculations. It allows for parsing of .pds and LHAPDF6 files and estimates PDF errors for Hessian and MC releases.
