| contents | We explore the connection of baryogenesis at temperatures below the electroweak scale and signals for long-lived particles at the LHC. The model features new SM singlets, with a long-lived fermion decaying to quarks to generate the baryon asymmetry. The model avoids strong flavor physics bounds while predicting a rich diquark phenomenology, monojet signals, and displaced vertices. We show how the displaced vertex signals can be probed at the HL-LHC. The large transverse production makes a strong physics case for constructing far detector experiments such as MATHUSLA, ANUBIS, and CODEX-b, complementary to the central and forward long-lived particle program. |
