TL;DR
This paper presents a model-independent phenomenological analysis of eta meson photoproduction on protons to estimate Breit-Wigner parameters of specific nucleon resonances, avoiding reliance on theoretical models.
Contribution
It introduces a purely statistical, model-independent method for extracting resonance parameters from experimental data.
Findings
Accurate estimates of Breit-Wigner parameters for S11(1535), S11(1650), and P11(1710) resonances.
Demonstrates the effectiveness of statistical procedures in resonance analysis.
Provides a new approach that reduces model dependence in resonance parameter estimation.
Abstract
Estimates of Breit-Wigner parameters of nucleon resonances were obtained by phenomenological analysis of eta meson photoproduction on protons performed completely by statistical procedures without appealing to theoretical models
