Model-independent analysis for determining mass splittings of heavy baryons

TL;DR

This paper uses heavy quark effective theory to analyze hyperfine mass differences in heavy hadrons, considering one-gluon exchange effects, and predicts masses of heavy baryons based on experimental data in a model-independent manner.

Contribution

It provides a novel, model-independent method to predict heavy baryon masses using HQET and experimental data, accounting for one-gluon exchange effects.

Findings

Predicted masses of certain heavy baryons.

Quantified hyperfine mass differences in heavy hadrons.

Validated predictions with existing experimental data.

Abstract

We study the hyperfine mass differences of heavy hadrons in the heavy quark effect theory (HQET). The effects of one-gluon exchange interaction are considered for the heavy mesons and baryons. Base on the known experimental data, we predict the masses of some heavy baryons in a model-independent way.
