Abstract We review the Nambu-Jona-Lasinio (NJL) approach to the dynamical breaking of
chiral symmetry in Quantum Chromodynamics (QCD). After a general overview of the …

The current status of theoretical studies on the quantum chromodynamics (QCD) phase
diagram at finite temperature and baryon chemical potential is reviewed with special …

Classically conformal Standard Model extensions predict an intriguing thermal history of the
early Universe. In contrast to the common paradigm, the onset of the electroweak phase …

We review recent developments and applications of the Nambu and Jona-Lasinio model
with three quark flavours, based on the SU (3) L⊗ SU (3) R⊗ U (1) V symmetry of QCD. The …

We present calculations of mesonic (quark-antiquark) modes in a generalized Nambu-Jona-
Lasinio model with three quark flavours. The effective interaction between quarks is …

Solutions of the self-consistent equation for fermion propagator in a vector-gluon model are
fully examined. The equation is characterized by a set of parameters, ie, the coupling …

A bstract The LHC and other experiments show so far no sign of new physics and long-held
beliefs about naturalness should be critically reexamined. We discuss therefore in this paper …

We investigate the possibilities of using measurements in present and future experiments on
heavy ion collisions to answer some longstanding problems in hadronic physics, namely …

We study the phase structure of QCD at finite temperature within a Polyakov-loop extended
quark–meson model. Such a model describes the chiral as well as the confinement …

We investigate the properties of constituent quarks, ie quarks dressed by their strong
interactions, in a generalized Nambu-Jona-Lasinio model with Nf= 3 flavours. In the Hartree …
