Some properties of two Nambu--Jona-Lasinio -type models with inputs from lattice QCD
P. Costa, C. A. de Sousa, M. C. Ruivo +3
We investigate the phase diagram of the so-called Polyakov--Nambu--Jona-Lasinio (PNJL) model at finite temperature and nonzero chemical potential. The calculations are performed in…

What Does Low Energy Physics Tell Us About The Zero Momentum Gluon Propagator
Pedro Costa, O. Oliveira, P. J. Silva
The connection between QCD, a nonlocal Nambu--Jona-Lasinio type model and the Landau gauge gluon propagator is explored. This two point function is parameterized by a functional fo…
