Welcome to the CJ downloads page!
The CJ (CTEQ-Jefferson Lab) Collaboration studies the quark and gluon structure of the nucleon by performing global QCD fits of parton distribution functions (PDFs). These parametrize a vast array of data including deep-inelastic lepton-nucleon scattering, proton-proton collisions (lepton pair creation, W-boson and jet production), and other reactions, with particular focus on the large-x region.
Programs and grids to calculate the CJ PDFs and structure functions are collected in the downloads/ folder, where more information and software usage can be found.
Note that LHAPDF grids can also be found from LHAPDF distribution.
