| Abstract: |
The observed dark matter-to-baryon ratio suggests a fundamental connection between the dark and visible sectors beyond gravitational interactions. I will first explain how a baryonic dark matter candidate, the sexaquark, can be produced through thermal and nonthermal mechanisms, while preserving the observed baryon asymmetry. I will show how sexaquarks as a large component of dark matter are constrained by current observational data, and stronger constraints can be set if antisexaquarks are present. I will then discuss a mechanism to simultaneously generate a baryon asymmetry and asymmetric dark matter in a wider range of masses through scattering interactions shortly after reheating, further exemplifying the dark matter and baryon connection. |
