Description
Self-interacting radiations are generic consequences of many BSM models. I present a comprehensive study of cosmological constraints on self-interacting light relics using cosmic microwave background and baryon acoustic oscillation data. In this talk, I will describe how to implement self-interacting radiation in the Boltzmann hierarchy and show results for different types of relics and interactions.
