We study what happens to the Nucleon, Delta and Omega baryons in the hadronic gas and the quark-gluon plasma, with particular interest in parity doubling and its emergence as the plasma is heated. This is done using simulations of lattice…
We establish that the charmed hadrons start dissociating at the chiral crossover temperature, ${T_{pc}}$, leading to the appearance of charm degrees freedom carrying fractional baryon number. Our method is based on analyzing the second and…
In recent years, several charmed baryons have been discovered, with more states likely to be found in the future. We investigate the spectra of singly and doubly charmed baryons on the lattice. The spin J=1/2 and J=3/2 states are calculated…
