Jianwei Qiu Associate Director for Theoretical & Computational Physics
Theory Center Director, Jefferson Lab
As the associate director for Theoretical and Computational Physics, Jianwei Qiu oversees a broad program of theoretical research in support of the physics studied by the Continuous Electron Beam Accelerator Facility (CEBAF) experimental program.
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.
