A Unified Numerical Study of Axion Stars: From the Nonrelativistic Regime to General Relativity
Parisa Arabameri, Paola Arias, Francisco Colipí-Marchant +1
Axion-star mass-radius relations are commonly computed using different orders of relativistic approximation, making it important to determine where these descriptions remain reliab…
From Rags to Jeans: Axion Miniclusters from Early matter domination
Ariel Angulo, Paola Arias, Nicolás Bernal +1
In an early matter-dominated era, density and temperature inhomogeneities of the radiation bath grow more efficiently than in the standard radiation-dominated history. If the axion…
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…
