Title: Electroweak Vacuum Metastability and Low-scale Inflation,
Abstract: We study the stability of the electroweak vacuum in low-scale inflation
models whose Hubble parameter is much smaller than the instability scale of the
Higgs potential. In general, couplings between the inflaton and Higgs are
present, and hence we study effects of these couplings during and after
inflation. We derive constraints on the couplings between the inflaton and
Higgs by requiring that they do not lead to catastrophic electroweak vacuum
decay, in particular, via resonant production of the Higgs particles.
