Lecture
This lecture discusses the naturalness problem in the UV completions of the Standard Model, exploring models where the Higgs mass is predicted to be small at the ground state (SUSY, Composite Higgs) and at the current metastable state (Anthropics, relaxion). The speaker presents an idea where the Higgs mass determines the universe's expansion, proposing a mechanism where the Higgs is coupled to a CFT with techni-quarks carrying SU(2) charges. The talk covers the CFT/RS model, the potential, and the cosmological dynamics related to the Higgs VEV. It concludes with a discussion on the light dilaton, its couplings, and the implications for cosmology and baryogenesis.
