pole mass calculation in a strong magnetic field and lattice constraints
Sidney S. Avancini, Ricardo L. S. Farias, Marcus Benghi Pinto +2
The neutral meson pole mass is calculated in a strongly magnetized medium using the SU(2) Nambu-Jona-Lasinio model within the random phase approximation (RPA) at zero tempera…
Reliability of the optimized perturbation theory in the 0-dimensional scalar field model
Dérick S. Rosa, R. L. S. Farias, Rudnei O. Ramos
We address the reliability of the Optimized Perturbation Theory (OPT) in the context of the 0-dimensional scalar field model. The effective potential, the self-energy and th…
Thermo-magnetic effects in quark matter: Nambu--Jona-Lasinio model constrained by lattice QCD
R. L. S. Farias, V. S. Timoteo, S. S. Avancini +2
The phenomenon of inverse magnetic catalysis of chiral symmetry in QCD predicted by lattice simulations can be reproduced within the Nambu--Jona-Lasinio model if the coupling~ o…
