Description
In this poster, we present a systematic bottom-up approach to effective field theory based on a minimal set of effective operators that lead to lepton number asymmetry generation. This process occurs simultaneously with dark matter production. A key component of the minimal scenario is the Weinberg operator, which contributes to both leptogenesis and neutrino masses. However, we show that the smallness of the neutrino mass implies a significant mass hierarchy within the dark sector of the theory. This poster is based on arXiv:2504.15164.
