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…
