Production of massive bosons from the decay of a massless particle beam
Ariel Arza
Taking a two interacting scalar toy model with interaction term , we study the production of particles coming from the decay of an asymptotic and highly occupied beam of…

Hidden Photon Dark Matter Interacting via Axion-like Particles
Paola Arias, Ariel Arza, Joerg Jaeckel +1
We investigate a scenario where the dark matter of the Universe is made from very light hidden photons transforming under a -symmetry. In contrast to the usual situation, ki…

How to suppress exponential growth -- on the parametric resonance of photons in an axion background
Ariel Arza, Thomas Schwetz, Elisa Todarello
Axion--photon interactions can lead to an enhancement of the electromagnetic field by parametric resonance in the presence of a cold axion background, for modes with a frequency cl…
