Title:“Freeze-In dark matter with messenger portals in low temperature reheating scenarios”

Date: Miércoles 3 de septiembre, 16:00 horas (Chile Continental)

Abstract: “In this talk we will motivate the production of dark matter through freeze-in mechanisms, focusing on two different realizations where messenger particles connect the dark sector to the Standard Model. In the first model, the axion plays the role of dark matter, while a dark photon acts as the mediator to the SM, defining the Pure Dark Axion Portal. In the second model, the dark matter candidate is the dark photon, and a pseudo-scalar particle serves as the messenger through two distinct interactions to the SM that give rise to both UV and IR freeze-in channels. These channels provide a rich phenomenology and shape the relic abundance. In both frameworks, a low reheating temperature plays a central role, not only in the dark matter production but also in opening possibilities for testing the models through experimental or observational signatures.”
