Photon polarization tensor in presence of constant and arbitrary electric field
Luis A. Hernández, Juan D. Martínez-Sánchez, R. Zamora
We compute the photon polarization tensor at one-loop order in the presence of a constant and uniform electric field. Our calculation is carried out for arbitrary field strength us…
Screening rho-meson mass in the presence of strong magnetic fields
Luis A. Hernández, Juan D. Martínez-Sánchez, R. Zamora
We study the screening mass of the neutral rho-meson in the presence of strong magnetic fields using the Kroll-Lee-Zumino (KLZ) model. The rho-meson self-energy is computed at one-…
Vortical effects and the critical end point in the Linear Sigma Model coupled to quark
Luis A. Hernández, R. Zamora
In this paper, we study the effects of vorticity on the QCD phase transition using the Linear Sigma Model coupled to quarks. By going beyond the mean-field approximation and incorp…
Magnetic corrections to the QCD coupling: strong field approximation
Gabriela Fernández, Luis A. Hernández, R. Zamora
We compute the 1-loop vertex function of the QCD coupling in the presence of an ultra intense magnetic field. From the vertex function, we extract the effective coupling and show t…
