Quark mass effects in the thermodynamical properties of an extended (P)NJL model
J. Moreira, J. Morais, B. Hiller +2
We analyze the thermodynamical properties of a system of strongly interacting particles at vanishing quark chemical potential in the framework of a recently developed extension of…
Thermodynamical properties of strongly interacting matter in a model with explicit chiral symmetry breaking interactions
J. Moreira, J. Morais, B. Hiller +2
We analyse the effects of the light and strange current quark masses on the phase diagram of QCD at finite temperature and vanishing baryonic chemical potential, computing the spee…
The effects of explicit chiral symmetry breaking multiquark interactions on the spin 0 and 1 meson nonets: the ruling of the vector mesons
Jorge Morais, Brigitte Hiller, Alexander A. Osipov
We have recently extended the scalar-pseudoscalar sector of a generalized NJL Lagrangian that includes all NLO non derivative interactions in Nc counting (including explicit symmet…
Strongly Interacting Matter Phase Diagram in the presence of Magnetic Fields in an Extended Effective Lagrangian Approach with Explicit Chiral Symmetry Breaking Interactions
J. Moreira, J. Morais, B. Hiller +2
Extensions of the NJL model which go beyond the original 4-quark interaction, which drives the dynamical mass generation, have proven to be quite successful in describing low energ…
Spin 1 low lying meson spectra and the subtle link to the spin 0 mesons
Jorge Morais, Brigitte Hiller, Alexander A. Osipov
An NJL-type three-flavor quark model with a complete set of explicit chiral symmetry breaking terms is extended to include vector and axial vector effective interaction terms. The…
A general framework to diagonalize vector--scalar and axial-vector--pseudoscalar transitions in the effective meson Lagrangian
Jorge Morais, Brigitte Hiller, Alexander A. Osipov
A new mathematical framework for the diagonalization of the nondiagonal vector--scalar and axial-vector--pseudoscalar mixing in the effective meson Lagrangian is described. This pr…
Masses of the lowest spin-0 and spin-1 meson nonets: explicit symmetry breaking effects
Jorge Morais, Brigitte Hiller, Alexander A. Osipov
We extend a known multi-quark three-flavor Lagrangian of the Nambu-Jona-Lasinio type, which includes a set of effective interactions proportional to the current quark masses, to in…
The phase diagram of the NJL model in the presence of explicit symmetry-breaking interactions
J. Morais, J. Moreira, B. Hiller +2
It is shown that the strange quark mass undergoes a first order transition in a generalized 3 flavor Nambu--Jona-Lasinio (NJL) Lagrangian which includes a complete set of explicit…
Strange quark matter in the presence of explicit symmetry breaking interactions
J. Moreira, J. Morais, B. Hiller +2
It is shown that a first order transition associated with a jump in the strange quark mass appears in a generalized 3 flavour Nambu--Jona-Lasinio (NJL) treatment of quark matter. T…
