Reanalysis of the heavy baryon states $\Omega_b$, $\Omega_c$, $\Xi'_b$, $\Xi'_c$, $\Sigma_b$ and $\Sigma_c$ with QCD sum rules

TL;DR

This paper reanalyzes various heavy baryon states using QCD sum rules, accounting for negative parity contributions, resulting in mass predictions that align well with experimental data.

Contribution

It provides a refined analysis of heavy baryon masses by subtracting negative parity contributions, improving agreement with experimental measurements.

Findings

Predicted masses match experimental data well

Negative parity contributions significantly affect mass calculations

Reanalysis improves understanding of heavy baryon structure

Abstract

In this article, we re-study the heavy baryon states $\Omega_b$, $\Omega_c$, $\Xi'_b$, $\Xi'_c$, $\Sigma_b$ and $\Sigma_c$ with the QCD sum rules, after subtracting the contributions from the corresponding negative parity heavy baryon states, the predicted masses are in good agreement with the experimental data.
