Abstract: We investigate the capabilities of the Nambu--Jona-Lasinio model to describe and reproduce fundamental vacuum properties of Quantum Chromodynamics, notably the hadronic spectrum. Mesons are described as quark-antiquark bound states at the level of the random… read more here.

DOI: 10.1103/physrevd.104.074026
Abstract: We investigate the properties of neutral and charged pions in a constant background magnetic field mainly at zero temperature within the Nambu–Jona-Lasinio model. In the previous calculations, the Ritus method, involving Schwinger phases in a… read more here.

DOI: 10.1103/physrevd.107.096017
Abstract: The Nambu--Jona-Lasinio model is widely used to study strong-interaction phenomena in the vacuum and quark matter. Since the model is nonrenormalizable, one needs to work within a specific regularization scheme to obtain finite results. Here… read more here.

DOI: 10.1103/physrevd.95.054005
Abstract: The Polyakov$-$Nambu$-$Jona-Lasinio model has been quite successful in describing various qualitative features of observables for strongly interacting matter, that are measurable in heavy-ion collision experiments. The question still remains on the quantitative uncertainties in the… read more here.
