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…
Automated Design of Salient Object Detection Algorithms with Brain Programming
Gustavo Olague, Jose Armando Menendez-Clavijo, Matthieu Olague +4
Despite recent improvements in computer vision, artificial visual systems' design is still daunting since an explanation of visual computing algorithms remains elusive. Salient obj…
Collision energy dependence of the critical end point from baryon number fluctuations in the Linear Sigma Model with quarks
Alejandro Ayala, Bilgai Almeida Zamora, J. J. Cobos-Martínez +4
We show that the Linear Sigma Model with quarks produces an effective description of the QCD phase diagram and of the system's equilibrium distribution properties that deviate from…
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…
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…
Gluon polarization tensor and dispersion relation in a weakly magnetized medium
Alejandro Ayala, Jorge David Castaño-Yepes, L. A. Hernández +2
We study the polarization and dispersion properties of gluons moving within a weakly magnetized background at one-loop order. To this end, we show two alternative derivations of th…
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…
Magnetic field dependence of nucleon parameters from QCD sum rules
C. A. Dominguez, Luis A. Hernández, Marcelo Loewe +2
Finite energy QCD sum rules involving nucleon current correlators are used to determine several QCD and hadronic parameters in the presence of an external, uniform, large magnetic…
Quark spin - thermal vorticity alignment and the Lambda, anti-Lambda polarization in heavy-ion collisions
Alejandro Ayala, David de la Cruz, L. A. Hernández +2
It has been proposed that the and polarizations observed in heavy-ion collisions are due to the interaction between quark spin and thermal vorticity. In this work…
Fluctuating temperature and baryon chemical potential in heavy-ion collisions and the position of the critical end point in the effective QCD phase diagram
Alejandro Ayala, Saul Hernandez-Ortiz, Luis A. Hernandez +2
We use the linear sigma model with quarks to locate the critical end point in the effective QCD phase diagram accounting for fluctuations in temperature and quark chemical potentia…
Relaxation time for the alignment between the spin of a finite-mass quark/antiquark and the thermal vorticity in relativistic heavy-ion collisions
Alejandro Ayala, David de la Cruz, L. A. Hernández +1
We study the relaxation time required for the alignment between the spin of a finite-mass quark/antiquark and the thermal vorticity, at finite temperature and baryon chemical poten…
Software System Design based on Patterns for Newton-Type Methods
Ricardo Serrato Barrera, Gustavo Rodríguez Gómez, Julio César Pérez Sansalvador +3
A wide range of engineering applications uses optimisation techniques as part of their solution process. The researcher uses specialized software that implements well-known optimis…
