QCD in Nuclear Processes at Jefferson Lab
نویسنده
چکیده
The scientific program at Jefferson Lab to probe the properties of QCD in the nuclear environment is outlined. The experimental facilities are described and recent results are presented including measurements of color transparency and medium modifications of vector mesons. The evidence for the onset of color transparency is modest and changes to the mass and width of the ρ meson in heavy nuclei are consistent with zero. Finally, the future prospects for the upgraded laboratory are discussed.

Nucleon hologram with exclusive leptoproduction
Hard exclusive leptoproductions of real photons, lepton pairs and mesons are the most promising tools to unravel the three-dimensional picture of the nucleon, which cannot be deduced from conventional inclusive processes like deeply inelastic scattering. Brief summary of talks given at 17th Summer School HUGS@CEBAF (Jefferson Lab, June 2002) Workshop “Exclusive processes at high momentum transf...
متن کاملRecent Results from Jefferson Lab
Recent results on studies of the structure of nucleons and nuclei in the regime of strong interaction QCD are discussed. Use of high current polarized electron beams, polarized targets, and recoil polarimeters, in conjunction with modern spectrometers and detector instrumentation allow much more detailed studies of nucleon and nuclear structure than has been possible in the past. The CEBAF acce...
متن کاملTesting QCD in the non-perturbative regime
This is an exciting time for strong interaction physics. We have a candidate for a fundamental theory, namely QCD, which has passed all the tests thrown at it in the perturbative regime. In the non-perturbative regime it has also produced some promising results and recently a few triumphs but the next decade will see enormous progress in our ability to unambiguously calculate the consequences o...
متن کاملv 2 2 3 Se p 20 02 SLAC - PUB - 9281 July 2002 Perspectives on Exclusive Processes in QCD ∗
Hard hadronic exclusive processes are now at the forefront of QCD studies, particularly because of their role in the interpretation of exclusive hadronic B decays, processes which are essential for determining the CKM phases and the physics of CP violation. Perturbative QCD and its factorization properties at high momentum transfer provide an essential guide to the phenomenology of exclusive am...
