Charm baryons at finite temperature on anisotropic lattices

TL;DR

This study examines how charm baryons' spectra change with temperature using anisotropic lattice QCD, providing insights into their behavior across the confinement-deconfinement transition and the effects of chiral symmetry restoration.

Contribution

It presents the first detailed temperature-dependent analysis of singly, doubly, and triply charmed baryons on anisotropic lattices, including the impact of chiral symmetry restoration.

Findings

Pseudocritical temperature can be estimated from charmed baryon correlators.

Parity doubling is not prominent near the pseudocritical temperature.

Charmed baryon spectra show temperature dependence across the confining phase.

Abstract

Singly, doubly and triply charmed baryons are investigated at multiple temperatures using the anisotropic FASTSUM 'Generation 2L' ensembles. We discuss the temperature dependence of these baryons' spectra in both parity channels with a focus on the confining phase. To further qualify the behaviour of these states around the pseudocritical temperature, we investigate the effect of chiral symmetry restoration for light quarks. We find that an estimate of the pseudocritical temperature can still be found from positive and negative-parity charmed baryon correlators, even when parity doubling itself is not very evident (as expected).
