Mass spectra of singly heavy baryons in a self-consistent chiral quark-soliton model

TL;DR

This paper calculates the mass spectra of singly heavy baryons using a self-consistent chiral quark-soliton model, incorporating rotational and strange quark mass corrections, and predicts the mass of the  baryon.

Contribution

It introduces a detailed calculation of heavy baryon masses within a chiral soliton framework, including second-order strange quark mass corrections, and provides new mass predictions.

Findings

Predicted the  baryon mass as 6081.9 MeV.

Successfully fitted classical masses to experimental data for all lowest-lying heavy baryons.

Demonstrated the importance of second-order strange quark mass corrections in mass calculations.

Abstract

We investigate the mass spectra of the lowest-lying singly heavy baryons, based on the self-consistent chiral quark-soliton model. We take into account the rotational $1/N_c$ and strange current quark mass ($m_{\mathrm{s}}$) corrections. Regarding $m_{\mathrm{s}}$ as a small perturbation, we expand the effective chiral action to the second order with respect to $m_{s}$. The mass spectra of heavy baryons are computed and compared with the experimental data. Fitting the classical masses of the heavy baryon to the center mass of each representation, we determine the masses of all the lowest-lying singly heavy baryons. We predict the mass of the $\Omega_b^*$ baryon to be 6081.9 MeV, when the second-order $m_{\mathrm{s}}$ corrections are included.
