Phase structure of 2+1-flavour QCD and the magnetic equation of state

Understand

We determine the chiral phase structure of $2+1$-flavour QCD in dependence of temperature and the light flavour quark mass with Dyson-Schwinger equations.

• Specifically, we compute the renormalised chiral condensate and its susceptibility.
• The latter is used to determine the (pseudo)critical temperature for general light current quark masses.
• In the chiral limit we obtain a critical temperature of about 141\,MeV.
