Reconstructed baryon transition current structure (N(1535) negative parity F1 form factor) via selective flattening: Insights from Patterson function analysis

Abstract

This study refines the reconstruction of the Dirac‑type transition current density of the N(1535) negative parity F1 resonance through selective flattening. The analysis reveals a compact positive core with a half‑maximum radius of 0.0339 fm, encircled by a diffuse negative shell. These features emphasize the highly localized spatial structure of the N(1535) resonance and provide direct empirical imaging of baryonic substructure.
