Description

We calculate the masses and decay widths of the excited N baryons. Our calculated masses of the 2S and 1P states are close to the experimental observations of N(1440) and N(1520), respectively. To further improve the reliability of our results, we implement Bayesian uncertainty refinement, and the optimized mass values for both states lie within the ranges reported by the PDG. Moreover, our predicted decay widths are consistent with other theoretical and experimental results.
