Constituent-quark model description of triply heavy-baryon nonperturbative lattice QCD data

TL;DR

This paper uses a constituent quark model to predict the spectra of triply heavy baryons and compares these predictions with recent high-precision lattice QCD data to evaluate the model's accuracy.

Contribution

It demonstrates that potential models can effectively describe triply heavy baryons, bridging lattice QCD results and constituent quark model predictions.

Findings

Model predictions agree with lattice QCD data for ground and excited states.

The approach helps reconcile different lattice QCD results.

Provides insights into the nonperturbative regime of QCD for heavy baryons.

Abstract

This paper provides results for the spectra of triply charmed and bottom baryons based on a constituent quark model approach. We take advantage of the assumption that potential models are expected to describe triply heavy baryons to a similar degree of accuracy as the successful results obtained in the charmonium and bottomonium sectors. The high precision calculation of the ground state and positive and negative parity excited states recently reported by nonperturbative lattice QCD provides us with a unique opportunity to confront model predictions with data. This comparison may also help to build a bridge between two difficult to reconcile lattice QCD results, namely, the lattice SU(3) QCD static three-quark potential and the recent results of nonperturbative lattice QCD for the triply heavy-baryon spectra.
