The phase diagram for the Nambu--Jona-Lasinio model with 't Hooft and eight-quark interactions
B. Hiller, J. Moreira, A. A. Osipov +1
It is shown that the endpoint of the first order transition line which merges into a crossover regime in the phase diagram of the Nambu--Jona-Lasinio model, extended to include the…
Impact of eight quark interactions on chiral phase transitions II: Thermal effects
B. Hiller, A. A. Osipov, J. Moreira +1
In this talk attention is drawn to thermal properties due to the addition of eight quark interactions in the standard chiral Nambu-Jona-Lasinio model (NJL) with…
Impact of eight-quark interactions in chiral phase transitions I: Secondary magnetic catalysis
A. A. Osipov, B. Hiller, A. H. Blin +1
The influence of a constant magnetic field on the order parameter of the four-dimensional Nambu and Jona-Lasinio model extended by the 't Hooft six-quark term and eight-quark inter…
Eight-quark interactions as a chiral thermometer
J. Moreira, A. A. Osipov, B. Hiller +2
A NJL Lagrangian extended to six and eight quark interactions is applied to study temperature effects (SU(3) flavor limit, massless case), and (realistic massive case). The transit…
Review of Scalar Mesons
D. V. Bugg
The formulae needed to parametrise sigma, kappa, a0(980) and f0(980) are reviewed. For sigma and kappa, the Adler zero due to Chiral Symmetry Breaking plays a crucial role. The f0(…
NJL with eight quark interactions: Chiral phases at finite T
B. Hiller, A. A. Osipov, J. Moreira +1
The thermodynamic potential and thermal dependence of low lying mass spectra of scalars and pseudoscalars are evaluated in a generalized Nambu -- Jona-Lasinio model, which incorpor…
Effects of Quark Interactions on Dynamical Chiral Symmetry Breaking by a Magnetic Field
Brigitte Hiller, Alexander A. Osipov, Alex H. Blin +1
It is shown how the strong interaction dynamics of a multi-quark Lagrangian affects the catalysis of dynamical symmetry breaking by a constant magnetic field in (3+1) dimensions. A…
