Abstract
We present a very minimal model for baryogenesis by a dark first-order phase transition. It employs a new dark gauge group with two doublet Higgs bosons, two lepton doublets, and two singlets. The singlets act as a neutrino portal that transfer the generated asymmetry to the Standard Model. The model predicts detectable by future experiments as well as possible signals from exotic decays of the Higgs and bosons and stochastic gravitational waves.
