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…

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…

Thermal and baryon density modifications to the -boson propagator: A road to describe the transfer of vorticity to spin in a nuclear environment in relativistic heavy-ion collisions

Alejandro Ayala, José Jorge Medina-Serna, Isabel Domínguez +2

In the context of the description of how the vortical motion, produced in peripheral heavy-ion collisions, is transferred to the spin of hadrons, we compute the -meson propagat…

Two-gluon one-photon vertex in a magnetic field and its explicit one-loop approximation in the intermediate field strength regime

Alejandro Ayala, Santiago Bernal-Langarica, Jorge Jaber-Urquiza +1

We find the general structure for the two-gluon one-photon vertex in the presence of a constant magnetic field. We show that, when accounting for the symmetries satisfied by the st…

Relaxation time for the alignment between quark spin and angular velocity in a rotating QCD medium

Alejandro Ayala, Santiago Bernal-Langarica, Isabel Domínguez Jiménez +4

We compute the relaxation times for massive quarks and anti-quarks to align their spins with the angular velocity in a rigidly rotating medium at finite temperature and baryon dens…
