We consider a light scalar dark matter candidate with mass in the GeV range whose p-wave annihilation is enhanced through a Breit-Wigner resonance. The annihilation proceeds in the s-channel via a dark photon mediator. We compute the temperature at which kinetic decoupling between dark matter and the primordial plasma occurs and show that including the effect of kinetic decoupling can reduce...
Ultralight dark matter, such as axion and dark photon, in the milli-eV mass range, is notoriously difficult to detect. It is too high in frequency for high-Q cavity resonators yet below the energy threshold of single-photon detectors. Our recent work (arXiv:2208.06519) showed that the cyclotron motion of trapped electrons can resonantly couple to dark photon and provide a powerful probe of...
Nowadays, the research in Beyond Standard Model (BSM) scenarios aimed at describing the nature of dark matter is a very active field. DarkPACK is a recently released software conceived to help to sudy such models. It can already compute the relic density in the freeze-out scenario, and its potential can be used to compute other observables. With the present contribution, I would like to...
Simplified t-channel dark matter models serve as a versatile and well-motivated framework for rich dark sectors that are widely studied by ongoing experimental and theoretical efforts. In this work, we investigate the impact of non-perturbative effects on the dark matter relic abundance for two representative models of this kind of models, focusing on regions of parameter space where...
