    Workshop on Key Issues in Hadron Physics
    Message from Nathan Isgur

    October 10, 2000

    Argonne National Lab, Bates Lab, Brookhaven National Lab, Jefferson Lab, and Los Alamos National Lab announce a limited attendance WORKSHOP ON KEY ISSUES IN HADRONIC PHYSICS. The purpose of the Workshop is to prepare a White Paper for the hadron physics community which lays out the key scientific issues of this field. Given that the character of the proton and neutron (and the other hadrons) as Nuclear Building Blocks ultimately determines all of standard Nuclear Physics, this subject has clearly become an essential component of the future of Nuclear Physics as recognized in the recent NAS/NRC decadal survey of the field ("the Schiffer Panel Report"). The White Paper is to be ready in time for the Town Meeting on Hadron Physics and Electron Beam Facilities scheduled for 1-4 Dec 2000 at Jefferson Lab, which itself folds into the preparation of the new Nuclear Physics Long Range Plan.

    The Workshop will be held at the Sanderling Inn and Resort north of Duck, North Carolina, from 05-10 Nov 2000 (arrival Sunday afternoon 05 November, departure Friday morning 10 November). Arrival via Norfolk International Airport (ORF) using a car rental will be convenient for many participants; the resort is approximately 2 hours south of Norfolk.

    The Organizing Committee for the meeting is:

    James Bjorken (SLAC)
    Roy Holt (ANL)
    Nathan Isgur (Jefferson Lab)
    Curtis Meyer (CMU)
    Jen-Chieh Peng (LANL)
    Eric Swanson (U Pitt)

    The agenda for the meeting consists of five half-day scientific sessions with all day Thursday devoted to preparing the first draft of the White Paper. Each scientific session will have a an Overview Speaker, a Discussion Leader, and a Scientific Secretary, selected by the Organizing Committee to at least begin to raise the issues to be discussed in the the session, to lead the discusion of them amongst the participants, and to record the consensus reached in a form that begins to define some of the actual text of the draft White Paper, respectively. The Organizers are currently recruiting people for these roles; the current status of this effort is recorded below. Note that there are no plans for additional talks: the Workshop is dedicated to producing the White paper and will not be a good venue for presenting results.

    The sessions are:

    MON. AMQCD Fundamentals (Negele, Wilczek, tba)
    - Confinement and vacuum structure
    - Spontaneously broken Chiral Symmetry
    - The $U_A$(1) problem
    MON. PMThe Quark Structure of Matter as Seen Using pQCD and Elastic Form Factors (Milner, Ji, Makins)
    - Hard Processes (DIS, DES, Drell-Yan, Hadron-Hadron Processes, ...)
    - Duality (Bjorken and Bloom-Gilman)
    - u bar u, d bar d, s bar s Elastic Form Factors
    TUES AMThe Quark Structure of Matter as Seen Using Spectroscopy (tba, Dytman, Barnes)
    - Heavy Quarkonia
    - Heavy Light Systems
    - Conventional Systems: N*s, light quarkonia, hybrids, glueballs
    TUES PMThe Quark Structure of Matter as Seen Using Chiral Dynamics (tba, McClelland, Moss)
    - The Pion Content of the Nucleons
    - The Pion Nucleon Sigma Term
    - Current Quark Masses
    WED AMModels of The Quark Structure of Matter (Shuryak, tba, Szczepaniak)
    - Quark Models
    - The Instanton Liquid Model
    - The Flux Tube Model
    - Schwinger-Dyson-Type Models
    - The Large Nc Limit
    WED PMAvailable for excursions (to the Wright Brothers Museum of the NPS, beachcombing, the dunes at Jockey's Ridge State Park,..).
    THURSDAY AM/PMAs stated earlier, ALL DAY THURSDAY will be devoted to producing the first draft of the White Paper, and for selecting the editorial board responsible during the period 13-22 November for transforming this first draft into the White Paper to be presented at the 01-05 December Long Range Plan Town Meeting.
