Leading order quark-antiquark-W-boson vertex in the presence of a magnetic field
Alejandro Ayala, Alejandro Lopez, Ana Julia Mizher +2
We compute the leading order modification to the quark-antiquark--boson vertex in the presence of a constant and uniform magnetic field, specifically for the case where the quar…
Chiral first order phase transition at finite baryon density and zero temperature from self-consistent pole masses in the linear sigma model with quarks
Alejandro Ayala, Bruno El-Bennich, Ricardo L. S. Farias +4
We use the two-flavor Linear Sigma Model with quarks as an effective description of QCD to investigate the nature of the chiral phase transition at finite baryon chemical potential…
Photon production from gluon splitting and fusion induced by a magnetic field in heavy-ion collisions
Alejandro Ayala, Santiago Bernal-Langarica, José Jorge Medina-Serna +1
In heavy-ion collisions, an excess in photon production, together with a larger than expected positive elliptic flow, has been observed, a phenomenon commonly referred to as the di…
Meson mixing effects on the speed of sound in isospin-imbalanced matter
Alejandro Ayala, Bruno S. Lopes, Ricardo L. S. Farias +1
We explore isospin imbalanced strongly interacting matter within the two-flavor Linear Sigma Model with quarks, an effective model for low-energy QCD. At one loop order, including…
Locating the critical end point using the linear sigma model coupled to quarks
A. Ayala, J. A. Flores, L. A. Hernandez +1
We use the linear sigma model coupled to quarks to compute the effective potential beyond the mean field approximation, including the contribution of the ring diagrams at finite te…
Inverse magnetic catalysis from the properties of the QCD coupling in a magnetic field
Alejandro Ayala, C. A. Dominguez, L. A. Hernandez +2
We compute the vacuum one-loop quark-gluon vertex correction at zero temperature in the presence of a magnetic field. From the vertex function we extract the effective quark-gluon…
Chiral Symmetry transition in the Linear Sigma Model with quarks: Counting effective QCD degrees of freedom from low to high temperature
Alejandro Ayala, Jorge David Castano-Yepes, J. J. Cobos-Martinez +3
We use the linear sigma model coupled to quarks, together with a plausible location of the critical end point (CEP), to study the chiral symmetry transition in the QCD phase diagra…
Weinberg sum rules at finite temperature
A. Ayala, C. A. Dominguez, M. Loewe +1
The saturation of the two Weinberg sum rules is studied at finite temperature, using recent independent QCD sum rule results for the thermal behaviour of hadronic parameters in the…
Inverse magnetic catalysis in the linear sigma model with quarks
Alejandro Ayala, M. Loewe, R. Zamora
We compute the critical temperature for the chiral transition in the background of a magnetic field in the linear sigma model, including the quark contribution and the thermo-magne…
Inverse magnetic catalysis for the chiral transition induced by thermo-magnetic effects on the coupling constant
Alejandro Ayala, M. Loewe, Ana Julia Mizher +1
We compute the one-loop thermo-magnetic corrections to the self-coupling in a model where charged scalars interact also with a constant magnetic field. The calculation is motivated…
