Heavy baryons with relativistic quarks

TL;DR

This study uses lattice QCD with relativistic quarks to compute energies of heavy baryons containing charm and bottom quarks, including the first relativistic treatment of bottom baryons.

Contribution

It provides the first fully relativistic lattice QCD analysis of heavy baryons with bottom quarks at the physical point.

Findings

Computed ground-state energies of various heavy baryons.

Included singly-, doubly-, and triply-heavy baryons.

First to investigate heavy baryons with relativistic bottom quarks.

Abstract

We present a lattice QCD study of heavy baryons containing charm and bottom quarks, with particular emphasis on the relativistic treatment of all valence quarks. We use $N_f=2+1+1$ HISQ ensembles at the physical point to compute ground-state energies of spin-$3/2^+$ baryons, including singly-, doubly-, and triply-heavy charmed and bottom baryons. This work represents the first investigation of heavy baryons using fully relativistic bottom quarks.
