Clockwork inflation with non-minimal coupling
Abstract We suggest a clockwork mechanism for a Higgs-like inflation with the non-minimal coupling term $$\xi \phi ^2 R$$ ξϕ2R . The seemingly unnatural ratio of parameters, $$\lambda /\xi ^2 \sim 10^{-10}$$ λ/ξ2∼10-10 of the self quartic coupling of the inflaton, $$\lambda $$ λ , and the non-minima...
