Magnetic Catalysis of charmonium in the vector channel

Cesareo A. Dominguez, Michael Koning, Luis A. Hernández

We investigate the impact of an external magnetic field on the vector charmonium system within the framework of Hilbert moment QCD sum rules. By incorporating magnetic corrections…

Inverse magnetic catalysis in the linear sigma model: a beyond mean field approach

Gabriela Fernández, Luis A. Hernández, Ana Mizher

We explore the restoration of chiral symmetry in the linear sigma model coupled to quarks under the influence of strong magnetic fields and finite temperature, incorporating screen…

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-…

Fermion propagator in a rotating environment

Alejandro Ayala, L. A. Hernández, K. Raya +1

We apply the exponential operator method to derive the propagator for a fermion immersed within a rigidly rotating environment with cylindrical geometry. Given that the rotation ax…
