Baryon Asymmetry ‣ Inflation : accelerated expansion of Universe - Solve horizon/flatness problems + Provide density perturbations. - Dilute unwanted relics, but also SM particles such as baryons . ‣ Baryogenesis : production of baryon asymmetry after inflation. η = n B - Baryon to photon ratio (BBN) → ' 6 £ 10 ° 10 n γ ➡ Baryogenesis from Inflation? - Reheating requires couplings btw inflaton and the SM particles.
