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…
Magnetic field-dependence of the neutral pion mass in the linear sigma model coupled to quarks: The weak field case
Alejandro Ayala, Ricardo L. S. Farias, S. Hernandez-Ortiz +3
We compute the neutral pion mass dependence on a magnetic field in the weak field approximation at one-loop order. The calculation is carried out within the linear sigma model coup…
Thermo-magnetic evolution of the QCD strong coupling
Alejandro Ayala, C. A. Dominguez, Saul Hernandez-Ortiz +4
We study the one-loop gluon polarization tensor at zero and finite temperature in the presence of a magnetic field, to extract the thermo-magnetic evolution of the strong coupling…
Thermal corrections to the gluon magnetic Debye mass
Alejandro Ayala, Jorge David Castaño-Yepes, C. A. Dominguez +5
We compute the gluon polarization tensor in a thermo-magnetic environment in the strong magnetic field limit at zero and high temperature. The magnetic field effects are introduced…
Aspects of the pseudo Chiral Magnetic Effect in 2D Weyl-Dirac Matter
Ana Julia Mizher, Saul Hernandez-Ortiz, Alfredo Raya +1
A connection is established between the continuum limit of the low-energy tight-binding description of graphene immersed in an in-plane magnetic field and the Chiral Magnetic Effec…
QCD phase diagram from chiral symmetry restoration: analytic approach at high and low temperature using the Linear Sigma Model with Quarks
Alejandro Ayala, Saul Hernandez-Ortiz, Luis A. Hernandez
We use the linear sigma model with quarks to study the QCD phase diagram from the point of view of chiral symmetry restoration. We compute the leading order effective potential for…
Prompt photon yield and elliptic flow from gluon fusion induced by magnetic fields in relativistic heavy-ion collisions
Alejandro Ayala, Jorge David Castano-Yepes, C. A. Dominguez +3
We compute photon production at early times in semi-central relativistic heavy-ion collisions from non-equilibrium gluon fusion induced by a magnetic field. The calculation account…
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…
The effective QCD phase diagram and the critical end point
Alejandro Ayala, Adnan Bashir, J. J. Cobos-Martinez +2
We study the QCD phase diagram on the plane of temperature T and quark chemical potential mu, modelling the strong interactions with the linear sigma model coupled to quarks. The p…
