Photon production from gluon splitting and fusion induced by a magnetic field of arbitrary strength in relativistic heavy-ion collisions
Alejandro Ayala, Santiago Bernal-Langarica, José Jorge Medina-Serna +1
We compute the yield and elliptic flow coefficient for photons produced during the pre-equilibrium stage of semi-central relativistic heavy-ion collisions from the gluon fusion and…
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…
Magnetic field modifications to the pion-quark vertex in the Linear Sigma Model with quarks
Alejandro Ayala, Flávia Fialho, Adrián Lara +2
We compute the modification to the quark-neutral pion vertex, induced by a constant and uniform magnetic field, using the Linear Sigma Model with quarks as a low energy effective t…
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…
Mass and coupling magnetic field dependence in a scalar theory with charged bosons from an environmentally friendly renormalization group analysis
Alejandro Ayala, Flávia Fialho, Ana Mizher
We compute the running of the mass of a neutral boson and of its self-coupling in a simple model describing the self-interaction of three scalars, one of them neutral and the other…
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…
