Analysis of the ${1\over 2}^+$ doubly heavy baryon states with QCD sum rules

TL;DR

This paper uses QCD sum rules to predict the masses of ${1/2}^+$ doubly heavy baryons, helping guide experimental searches at major particle physics facilities.

Contribution

It introduces a method to subtract ${1/2}^-$ state contributions, providing more accurate mass predictions for ${1/2}^+$ doubly heavy baryons.

Findings

Predicted masses for $ ext{Omega}_{QQ}$ and $ ext{Xi}_{QQ}$ baryons.

Guidance for experimental detection at Tevatron, LHCb, and PANDA.

Enhanced understanding of doubly heavy baryon spectrum.

Abstract

In this article, we study the ${1\over 2}^+$ doubly heavy baryon states $\Omega_{QQ}$ and $\Xi_{QQ}$ by subtracting the contributions from the corresponding ${1\over 2}^-$ doubly heavy baryon states with the QCD sum rules, and make reasonable predictions for their masses. Those doubly heavy baryon states maybe observed at the Tevatron, the LHCb and the PANDA.
