Magnetic field-dependence of the neutral pion mass in the linear sigma model coupled to quarks: The weak field case
Alejandro Ayala, Ricardo L. S. Farias, S. Hernandez-Ortiz +3
We compute the neutral pion mass dependence on a magnetic field in the weak field approximation at one-loop order. The calculation is carried out within the linear sigma model coup…

Thermo-magnetic evolution of the QCD strong coupling
Alejandro Ayala, C. A. Dominguez, Saul Hernandez-Ortiz +4
We study the one-loop gluon polarization tensor at zero and finite temperature in the presence of a magnetic field, to extract the thermo-magnetic evolution of the strong coupling…
