Abstract: A rotation in the axion field space was shown capable of addressing cosmological mysteries, including the baryon asymmetry, dark matter, and cosmic perturbations. This dynamics may naturally arise as a result of quantum gravity effects and cosmic inflation. An example of such baryogenesis is called lepto-axiogenesis, where the axion rotation generates the lepton asymmetry via right-handed neutrinos, which is subsequently reprocessed into baryon number by electroweak sphaleron processes. This talk will focus on a new avenue where axion rotations can ameliorate the Hubble tension without exacerbating the S_8 tension while also explaining the observed baryon asymmetry of the Universe via lepto-axiogenesis. This model predicts heavy neutral leptons that may be within reach of future lepton colliders, the high-luminosity LHC, and SHiP.
