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…
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-…
Magnetic field dependence of the neutral pion longitudinal screening mass in the linear sigma model with quarks
Alejandro Ayala, Ricardo L. S. Farias, L. A. Hernández +4
We use the linear sigma model with quarks to study the magnetic-field-induced modifications on the longitudinal screening mass for the neutral pion at one-loop level. The effects o…
Chiral symmetry restoration in a rotating medium
Irving I. Gaspar, Luis A. Hernández, Renato Zamora
We study the nature of the chiral symmetry restoration within the Yukawa model with spontaneous symmetry breaking. We work with scalar and fermion fields which are subject to the e…
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…
Anisotropic photon emission from gluon fusion and splitting in a strong magnetic background I: The two-gluon one-photon vertex
Alejandro Ayala, Jorge David Castaño-Yepes, L. A. Hernández +3
Having in mind the pre-equilibrium stage in peripheral heavy-ion collisions as a possible scenario for the production of electromagnetic radiation, we compute the two-gluon one-pho…
Plasma screening and the critical end point in the QCD phase diagram
Alejandro Ayala, Bilgai Almeida Zamora, J. J. Cobos-Martínez +4
In heavy-ion collisions, fluctuations of conserved charges are known to be sensitive observables to probe criticality for the QCD phase transition and to locate the position of the…
Hadronic contribution to the running QED coupling at the Z-boson mass scale
Cesareo A. Dominguez, Luis A. Hernández
An update is described of a model independent method to determine the hadronic contribution to the QED running coupling at the Z-boson mass scale, . The…
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…
