Hadronic matter under strong magnetic fields: matching effective models to lattice QCD |
|
Résumé |
We try to modify the NJL model in a way it matches lattice QCD calculations for the quark
condensates and the neutral pion mass. The idea is to make the NJL coupling constant to
depend on the temperature and the magnetic field since a fixed coupling does not give the
same description of the phase transition as lattice QCD simulations. By making a fit, we
determine a thermo-magnetic coupling constant and compute thermodynamic quantities. Our
results show a good agreement with the lattice results for the condensates and the pion mass
under strong magnetic fields. We also show some results at zero temperature and finite
densities and magnetic fields for zero-strangeness isospin-symmetric and charge neutral
beta-equilibrated neutron-star matter. |
