Analysis of the ${3\over 2}^+$ heavy and doubly heavy baryon states with QCD sum rules

TL;DR

This paper uses QCD sum rules to analyze and predict the masses of various ${3/2}^+$ heavy and doubly heavy baryon states, accounting for contributions from negative parity states.

Contribution

It provides new mass predictions for ${3/2}^+$ heavy baryons by subtracting negative parity contributions using QCD sum rules.

Findings

Predicted masses for ${3/2}^+$ heavy baryons.

Method to subtract negative parity contributions.

Enhanced understanding of heavy baryon spectrum.

Abstract

In this article, we study the ${3\over 2}^+$ heavy and doubly heavy baryon states $\Xi^*_{cc}$, $\Omega^*_{cc}$, $\Xi^*_{bb}$, $\Omega^*_{bb}$, $\Sigma_c^*$, $\Xi_c^*$, $\Omega_c^*$, $\Sigma_b^*$, $\Xi_b^*$ and $\Omega_b^*$ by subtracting the contributions from the corresponding ${3\over 2}^-$ heavy and doubly heavy baryon states with the QCD sum rules, and make reasonable predictions for their masses.
