Dark energy from gravitational corrections

TL;DR

This paper proposes that dark energy may primarily originate from gravitational corrections to vacuum energy, assuming classical gravity does not fully couple to vacuum energy, especially in the context of terascale supersymmetry.

Contribution

It introduces a novel perspective that gravitational corrections can account for dark energy, assuming a specific decoupling of vacuum energy from classical gravity.

Findings

Dark energy may stem from gravitational corrections to vacuum energy.

Classical gravitational fields might not couple fully to vacuum energy.

Terascale supersymmetry supports the proposed mechanism.

Abstract

We study physics concerning the cosmological constant problem in the framework of effective field theory and suggest that a dominant part of dark energy can originate from gravitational corrections of vacuum energy, under the assumption that the classical gravitational fields do not couple to a large portion of the vacuum energy effectively, in spite of the coupling between graviton and matters at a microscopic level. Our speculation is excellent with terascale supersymmetry.
