Description
We consider the cosmological relaxation of the Higgs mass and the cosmological constant due to the four-form fluxes in four dimensions. We introduce non-minimal four-form couplings for reheating the Universe after the last membrane nucleation and propose some simple examples with a pseudo-scalar or a complex singlet scalar field. We also discuss the implications of the non-minimal four-form coupling to gravity for flattening the inflaton potential in chaotic inflation models with a pseudo-scalar field.
