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 b...
