Ground states of all mesons and baryons in a quark model with Hidden Local Symmetry

TL;DR

This paper extends a chiral quark model with Hidden Local Symmetry to include the s quark, successfully reproducing known hadron spectra and predicting new states for future experimental validation.

Contribution

The paper introduces an extended SU(3) chiral quark model with Hidden Local Symmetry that accurately models ground state hadron masses and predicts previously unobserved states.

Findings

Mass spectra of known mesons and baryons are well reproduced.

Predicted masses of one meson and twenty baryons for future experiments.

Model provides a unified framework for u, d, s, c, and b quark interactions.

Abstract

We extend the chiral quark model for $u$, $d$, $c$ and $b$ quarks with vector mesons, which we proposed in the previous analysis, to a model with the $s$ quark. We include the nonet pseudo-scalar and vector mesons together with the singlet scalar meson based on the SU(3)$_L \times$SU(3)$_R$ chiral symmetry combined with the Hidden Local Symmetry, which mediate force among $u$, $d$ and $s$ quarks. We fit the model parameters to the known ground state mesons and baryons. We show that the mass spectra of those hadrons are beautifully reproduced. We predict the masses of missing ground states, one meson and twenty baryons, which will be tested in the future experiment.
