The Jefferson Lab Angular Momentum (JAM) Collaboration is an enterprise involving theorists, experimentalists, and computer scientists from the Jefferson Lab community using QCD to study the internal quark and gluon structure of hadrons and nuclei.
JAM has a number of parton distribution function and fragmentation function sets publicly available in LHAPDF format, which can be accessed by downloading the tarball files here. Please refer to the LHAPDF website for instructions on how to use its interface.
The following PDF/FF sets are available with the corresponding LHAPDF ID numbers:
The Spectator Tagging Project develops the capabilities for high-energy electron scattering experiments with polarized light ions (deuteron 2H, 3He) and detection of spectator nucleons (protons, neutrons) at a future Electron-Ion Collider (EIC). Such experiments address basic questions of nuclear and strong interaction physics:
Event generators and analysis tools for electron-deuteron collisions with spectator nucleon tagging are being developed for process simulations at EIC. The materials are presently organized in the following categories:
