Hyperons in thermal QCD: A lattice view

Understand

The hadron resonance gas (HRG) is a widely used description of matter under extreme conditions, e.g.

• in the context of heavy-ion phenomenology.
• Commonly used implementations of the HRG employ vacuum hadron masses throughout the hadronic phase and hence do not include possible in-medium effects.
• Here we investigate this issue, using nonperturbative lattice simulations employing the FASTSUM anisotropic Nf=2+1 ensembles.
