Abstract
We describe a minimal extension of the standard model (SM) by three right-handed neutrinos, a scalar doublet, and a scalar singlet (the “”) which serves as an existence proof that weakly coupled high-scale physics can naturally explain phenomenological shortcomings of the SM. The can explain neutrino masses, baryogenesis, the strong problem, and dark matter, and remains calculably natural despite a hierarchy of scales up to . It predicts a SM-like Higgs boson (maximally) TeV-scale scalar states, intermediate-scale hierarchical leptogenesis (), and axionic dark matter.
