Low-energy etaN interactions: scattering lengths and resonance parameters

Authors

Description

We consider the impact of two recent pi- p-->eta n measurements on the etaN scattering length and etaN branching fractions for the N(1535) and N(1520) resonances within a coupled-channel analysis of piN elastic scattering and etaN production data. The sensitivity of these results to model input is also explored.
