Split Two-Higgs Doublet and Neutrino Condensation Motivations: • Coincidence between the very small neutrino mass scale and dark energy scale. Observed dark energy scale (10^{-3} eV)^4 Consequence: Two-Higgs doublet with vevs greatly split. Dynamical dark energy fields
Main points Neutrino mass was given by the other set of higgs field from neutrino condensation without see-saw mechanism Very tiny Stan\betas due to greatly split vevs The dynamically generated light higgs field is responsible for dark energy field
Main Points: • Neutrino mass was given by the other set of higgs field from neutrino condensation without see-saw mechanism. • Very tiny $tan\beta$ due to greatly split vevs. • The dynamically generated light higgs field is responsible for dark energy field
