Dark photon dark matter from flattened axion potentials
Hong-Yi Zhang, Paola Arias, Andrew Cheek +3
Dark photons can be resonantly produced in the early universe via their coupling to an oscillating axion field. However, this mechanism typically requires large axion--dark photon…
Probing displaced (dark)photons from low reheating freeze-in at the LHC
Paola Arias, Bastián Díaz Sáez, Lucía Duarte +3
We extend the Standard Model (SM) by introducing a gauge boson and a real pseudo-scalar field, both odd under a symmetry. The resulting low-energy spectrum c…
Freezing-in the Pure Dark Axion Portal
Paola Arias, Bastián Díaz Sáez, Joerg Jaeckel
A symmetry under which "dark'' and "visible'' fields transform differently can further seclude already dark particles. In a dark sector consisting of an axion-like particle a…
FIMP Dark Matter in bulk viscous non-standard cosmologies
Esteban González, Carlos Maldonado, N. Stefanía Mite +1
In this paper, we revisit the extension of the classical non-standard cosmological model in which dissipative processes are considered through a bulk viscous term in the new field…
WIMP dark matter in bulk viscous non-standard cosmologies
Esteban González, Carlos Maldonado, N. Stefanía Mite +1
In this paper, we explored an extension of the classical non-standard cosmological scenario in which the new field, , which interacts with the radiation component in the early u…
Rescuing The Primordial Black Holes all-Dark Matter Hypothesis from The Fast Radio Bursts Tension
Dorian W. P. Amaral, Enrico D. Schiappacasse
Primordial black holes (PBHs) as an all-dark matter (DM) hypothesis has recently been demotivated by the prediction that these objects would source an excessive rate of fast radio…
Magnetic field dependence of the neutral pion longitudinal screening mass in the linear sigma model with quarks
Alejandro Ayala, Ricardo L. S. Farias, L. A. Hernández +4
We use the linear sigma model with quarks to study the magnetic-field-induced modifications on the longitudinal screening mass for the neutral pion at one-loop level. The effects o…
The Yukawa potential under weak magnetic field
Fabio L. Braghin, Marcelo Loewe, Cristian Villavicencio
Weak magnetic field induced corrections for the Yukawa potential due to one pion exchange between two constituent quarks (nucleons) are presented. For that, the constant magnetic f…
Nucleon axial-vector coupling constant in magnetar environments
C. A. Dominguez, Marcelo Loewe, Cristian Villavicencio +1
The nucleon axial-vector coupling constant is studied in the presence of an external magnetic field, and in dense nuclear environments, to emulate nuclear matter in magnetars…
Revisiting signatures of thermal axions in nonstandard cosmologies
Paola Arias, Nicolás Bernal, Jacek K. Osiński +2
We revisit the formation of a thermal population of hadronic axions in nonstandard cosmologies, in light of the recent developments in obtaining continuous and smooth interaction r…
