Chiral models with Polyakov loop (PNJL and PQM)
- reproduce the lattice EoS
- provide physical understanding of lattice
results - make predictions for quantities not (yet)
accessible on the lattice (masses, transport
coefficients..) - can be extended to finite chemical potential
(test lattice procedures) - provide guidance for lattice extrapolations to
physical quark masses - assess critical behavior in the (T,m)-plane
- guide truncation schemes for Dyson-Schwinger
studies
