Hadronic Physics Group

The research program of the Hadronic Physics Group focuses on the use of the electromagnetic interaction to probe the structure of nucleons, few-nucleon systems, and complex nuclei.

A major component of the group's activities has been and will continue to be situated at the Bates Linear Accelerator Center. Though the experimental nuclear physics program at Bates ended in 2005 with the successful completion of the BLAST experiment; analysis of the BLAST data is ongoing. Also the Bates facility will continue to be a resource in detector and accelerator development in support of the group's activities at other laboratories.

The group currently plays a major role in numerous experiments at other laboratories:

• At the Brookhaven National Laboratory the STAR experiment studies the formation and characteristics of quark-gluon plasma though the particular interest of the Hadron Physics Group is with the spin structure of the proton and especially the gluon spin distribution within the proton.

• The QWEAK experiment at the Thomas Jefferson Laboratory in Newport News, VA will make a precision measurement of parity violating electron scattering on protons to measure the proton's weak charge to test the Standard Model predictions. The LNS Hadronic Physics Group is also involved with other experiments at JLAB: HAPPEX, PRIMEX, E93-038, E04-110, and others.

• Experiments at the Mainz Microtron MAMI, study the contribution of strange quarks to the proton form factor A4 Collaboration and study pp0 production near threshold as a check of chiral perturbation theory A1 Collaboration

• A new experiment at the HIGS facility at TUNL in Durham , NC will also study p0 production to test chiral perturbation theory.

• At the Los Alamos Neutron Science Centre (LANSCE) the group is involved in experiments studying the structure of few nucleon systems and the role of three nucleon forces.
