abstract

The $SU(3)$ chiral effective lagrangian at next-to-leading order is applied to the S-wave meson-baryon interaction in the energy range around the $\eta N$ threshold. Potentials are derived from this lagrangian and used in a coupled channel calculation of the $\pi N$, $\eta N$, $K \Lambda$, $K \Sigma$ system in the isospin-$1/2$, $l=0$ partial wave. Using the same parameters as obtained from a fit to the low energy $\overline{K} N$ data it is found that a quasi-bound $K \Sigma$-state is formed, with properties remarkably similar to the $S_{11}(1535)$ nucleon resonance. In particular, we find a large partial decay width into $\eta N$ consistent with the empirical data.

  1. Hyperon non-leptonic decays in relativistic Chiral Perturbation Theory with resonances

    hep-ph 2026-04 unverdicted novelty 7.0 of 10

    Relativistic ChPT at NLO with resonance saturation yields a good combined fit to hyperon non-leptonic s- and p-wave decay amplitudes.

  2. Spectroscopic and femtoscopic insights into vector-baryon interactions in the strangeness $-1$ sector

    hep-ph 2025-07 conditional novelty 6.0 of 10

    The authors predict three Lambda* and two Sigma* resonances from vector-baryon interactions and provide femtoscopy correlation functions for six channels in the S=-1 sector.

  3. Off-shell ambiguities in correlation functions: strategies to minimize them

    hep-ph 2025-06 conditional novelty 5.0 of 10

    For meson-baryon pairs tied to the N*(1535), off-shell ambiguities change correlation functions by only 2-3% in chiral models, and can be partly absorbed by adjusting the source size.

  4. Hadron Spectroscopy: Experimental Overview

    nucl-ex 2026-07 unverdicted
