Workshop A1
Hadronic Physics with Hadronic Beams at AGS: Baryons, Hyperons, and Pentaquarks
Location: Room B, Berkner Hall, Bldg. 488
Date: May 11, 2004
Organizers: Simon Capstick, Joseph Comfort, Mark Manley, Winston Roberts, and Mike Sadler
Local Contact: Winston Roberts
Description: The purpose of the workshop is to bring together theorists, experimentalists and phenomenologists with an interest in hadronic physics experiments with hadronic beams. Such experiments would provide complementary information that is crucial for the detailed understanding and interpretation of photoproduction and electroproduction experiments carried out at Jefferson Lab. Experiments with state-of-the-art detectors would have a high potential for discovering new high-mass baryons that have not been seen in older experiments. Such discoveries will shed light on the nature of the effective degrees of freedom and their interactions in low-energy QCD, and will help to resolve important issues, such as the possibility of chiral symmetry restoration higher in the baryon spectrum leading to parity doublets. Furthermore, such experiments can be pivotal in repudiating the reported pentaquark states, or confirming them and shedding further light on their spectroscopy, as well as in exploring other important issues in the structure of baryons and mesons.
The workshop can be viewed as the essential first step needed in the planning of such experiments. While a few talks will be presented, it is expected that much of the time allowed for the workshop will be spent in open discussion aimed at articulating the physics questions that such experiments can answer, determining the feasibility of performing such experiments at the AGS, and identifying the fiscal and physical resources needed for carrying out such experiments.
