Impact of muons on the bulk viscosity of neutron star matter metamodels
José Luis Hernández, Cristina Manuel, Laura Tolos
Recent studies invoke a unified description of different neutron star observables using metamodels, which parametrize the equation of state of neutron star matter close to nuclear…
QCD equation of state at finite isospin density from the linear sigma model with quarks: The cold case
Alejandro Ayala, Aritra Bandyopadhyay, Ricardo L. S. Farias +2
We use the two-flavor linear sigma model with quarks to study the phase structure of isospin asymmetric matter at zero temperature. The meson degrees of freedom provide the mean fi…
Magnetic field dependence of the neutral pion mass in the linear sigma model with quarks: The strong field case
Alejandro Ayala, José Luis Hernández, L. A. Hernández +2
We use the linear sigma model with quarks to find the magnetic field-induced modifications to the neutral pion mass at one-loop level. The magnetic field effects are introduced by…
Magnetic corrections to the boson self-coupling and boson-fermion coupling in the linear sigma model with quarks
Alejandro Ayala, José Luis Hernández, L. A. Hernández +2
We compute the magnetic field-induced modifications to the boson self-coupling and the boson-fermion coupling, in the static limit, using an effective model of QCD, the linear sigm…
