In this talk, I explore the connection of baryogenesis at temperatures below the electroweak scale and signals associated with long-lived particles at the LHC. Some models of low-temperature baryogenesis can avoid strong flavor physics bounds while predicting a rich diquark phenomenology, monojet signals, and displaced vertices. On the model-building side, I discuss simple implementations of baryogenesis with and without the spontaneous breaking of global baryon number. Finally, I entertain the idea that some LHC anomalies could be linked to these models in the context of R-parity violating supersymmetry.
