Clockwork inflation with non-minimal coupling

We suggest a clockwork mechanism for a Higgs-like inflation with the non-minimal coupling term phi 2R. The seemingly unnatural ratio of parameters, /2 approximate to 10-10 of the self quartic coupling of the inflaton, , and the non-minimal coupling, , is understood by exponential suppression of by the clockwork mechanism, instead of a large non-minimal coupling. The portal interaction between the inflaton and the Standard Model (SM) Higgs doublet is introduced as a source of reheating and the inflaton mass. Successful realization of inflation requires that the inflaton gets a mass around (sub) GeV scale, which would lead to observable consequences depending on reheating process and its lifetime.
