Effective Fermion-Photon Vertex in a Rotating Relativistic Medium: Tree-Level Structure
Jorge David Castaño-Yepes, Alejandro Ayala, J. E. Martínez-Herrera +1
We study the tree-level fermion-photon effective vertex for on-shell particles in a relativistic environment undergoing rigid rotation at zero temperature. The rotational backgroun…
Photon Quantization and Propagator in Rotating Coordinates
Alejandro Ayala, Santiago Bernal-Langarica, Jorge David Castaño-Yepes +1
We construct the quantized electromagnetic field and the corresponding photon propagators in a rigidly rotating cylindrical reference frame. Starting from covariant Maxwell theory,…
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…
Excitation function for global Λpolarization in relativistic heavy ion collisions with the Core Corona model
Alejandro Ayala, José Jorge Medina Serna, Isabel Domínguez +1
We compute the excitation function of the global polarization in semicentral heavy-ion collisions within a Core--Corona framework, where the interaction region is described as…
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 propagato…
Estimate for the neutrino magnetic moment from pulsar kick velocities induced at the birth of strange quark matter neutron stars
Alejandro Ayala, Santiago Bernal-Langarica, Daryel Manreza-Paret
We estimate the magnetic moment of electron neutrinos by computing the neutrino chirality flip rate that can occur in the core of a strange quark matter neutron star at birth. We s…
Influence of magnetic field-induced anisotropic gluon pressure during pre-equilibrium in heavy-ion collisions: A faster road towards isotropization
A. Ayala, A. Mizher
Magnetic fields of a large intensity can be generated in peripheral high-energy heavy-ion collisions. Although their intensity drops fast and, moreover, it is not clear whether the…
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…
Collision energy dependence of source sizes for primary and secondary pions at NICA energies
Alejandro Ayala, Santiago Bernal-Langarica, Isabel Dominguez +2
We study the evolution of the two-pion correlation function parameters with collision energy in the context of relativistic heavy-ion collisions within the NICA energy range. To th…
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…
Collision energy dependence of the critical end point from baryon number fluctuations in the Linear Sigma Model with quarks
Alejandro Ayala, Bilgai Almeida Zamora, J. J. Cobos-Martínez +4
We show that the Linear Sigma Model with quarks produces an effective description of the QCD phase diagram and of the system's equilibrium distribution properties that deviate from…
Two-component source to explain and global polarization in non-central heavy-ion collisions
A. Ayala, E. Cuautle, I. Domínguez +3
The STAR Beam Energy Scan program has found a difference in the global polarization of s and s produced in collisions. This difference is larger for lower center…
