Chiral Dynamics
The chiral symmetry present in the QCD Lagrangian along with Goldstone's theorem makes is possible to obtain an approximate QCD solution at low energies using an effective field theory known as chiral perturbation theory (ChPT) or Chiral Dynamics. Topics which will be discussed at this workshop are : Goldstone Boson Dynamics, Hadron Structure and Meson-Baryon Interactions, Few-Body Physics, and Lattice QCD and Chiral Perturbation Theory. In addition to the plenary talks, these topics will be the focus of three different working groups:

| Goldstone Boson Dynamics | Gilberto Colangelo and Simona Giovannella |
| Hadron Structure & Meson-Baryon Interactions | Thomas Hemmert, Jerry Feldman, and Alan Nathan |
