Extraction of resonance parameters from meson production reaction

Abstract: 

We have developed an analytic continuation method for extracting parameters of nucleon resonances within a Hamiltonian formulation of meson-nucleon reactions. The method was tested for simple solvable models and then applied for our recent coupled channels model (πN, ηN, πΔ, ρN, and σN) of the πN and γ*N reactions. The resonance pole positions and their properties are studied for P33 and P11 channels.
