Findings

Higgs mass and couplings are constrained by inflationary conditions.

Dark matter self-coupling affects inflation dynamics.

Quantum effects of the singlet influence inflationary predictions.

Abstract

A minimal candidate for dark matter is provided by a stable standard model singlet hermitian scalar field. The quantum mechanical effects of this singlet are explored in a model where the standard model Higgs boson has a large non-minimal coupling to the Ricci scalar and plays the role of the inflaton. Imposition of the slow roll inflation cosmological constraints restricts the allowed values of the Higgs boson mass, its coupling to the dark matter and the dark matter self-coupling.
