  1. Dynamical coupled channel analysis Excited Baryon Analysis Center Bruno Julia-Diaz, T.-S. Harry Lee, Akihiko Matsuyama, Mark Paris, and Toru Sato • Objective: • Complete analysis and interpretation of N* resonance data to address DOE 2009 milestone • Method: • Analysis: Solve dynamical coupled channel equations in Hamiltonian formalism (Sato-Lee model) • Interpretation: Ab-initio calculations of N* strong and electromagnetic transition form factors

  2. N* interpretation and modeling Excited Baryon Analysis Center Bruno Julia-Diaz, T.-S. Harry Lee, Akihiko Matsuyama, Mark Paris, and Toru Sato • Model resonance structure calculations: • Variational Monte Carlo (VMC) • Green’s function Monte Carlo (GFMC) • Relativistic dynamics • Potential model fits to data • Hamiltonian formalism • Strong and electromagnetic transitions • Recent results: • VMC pentaquark study • MWP PRL 95,202002 (2005)
