Natural scale of cosmological constant in seesaw mechanism with broken SUSY

TL;DR

This paper proposes that the cosmological constant's value is intrinsically linked to the supersymmetry breaking scale through a seesaw mechanism involving two vacuum states, offering a new perspective on its small observed value.

Contribution

It introduces a novel seesaw mechanism connecting the cosmological constant to supersymmetry breaking, providing a natural explanation for its small scale.

Findings

The cosmological constant scale is set by SUSY breaking parameters.

A seesaw mechanism explains the smallness of the cosmological constant.

The framework links vacuum stability to cosmological observations.

Abstract

The cosmological constant is inherently determined by the scale of breaking down supersymmetry in the mechanism of seesaw fluctuations of two vacuum-states.
