We consider the cosmological relaxation of the Higgs mass and the cosmological constant due to the four-form fluxes in four dimensions. We present a general class of models with a singlet scalar field containing four-form couplings where the Higgs mass is relaxed to a right value and the Universe reheats to a sufficiently high reheating temperature after the last membrane nucleation. We also discuss some of interesting features in the cases of singlet scalar fields with non-minimal or minimal couplings to gravity and show how the new scalar fields can play a role for dark matter production.

  1. Chaotic inflation with four-form couplings

    hep-ph 2019-08 conditional novelty 5.0 of 10

    A four-form flux that couples both to a pseudo-scalar inflaton and to gravity produces a plateau inflaton potential whose spectral index and tensor-to-scalar ratio agree with current CMB data.

  2. Relaxation of Higgs mass and cosmological constant with four-form fluxes and reheating

    hep-ph 2019-08 conditional novelty 5.0 of 10

    Four-form flux can relax the Higgs mass and cosmological constant, and a new scalar from the induced R^2 term can act as the inflaton to reheat the Universe.
