Gonzalo Alonso-Álvarez BNL Forum 2019 Main ideas 1. Baryogenesis and dark matter are linked. 2. The baryon asymmetry is related to B-meson observables. 3. SUSY theory contains all the ingredients for the mechanism. 4. Fully testable model: flavor, collider & astrophysical observables. Gonzalo Alonso-Álvarez BNL Forum 2019 Outline 1. The mechanism 2. New particles & SUSY model 3. Flavor, collider & astrophysical observables 4. Summary & Outlook Gonzalo Alonso-Álvarez BNL Forum 2019 1.
