Reconsidering a higher-spin-field solution to the main cosmological constant problem

TL;DR

This paper proposes a model with two massless vector fields that dynamically cancel the cosmological constant, leading to a stable Minkowski spacetime without affecting local gravity, thus addressing the cosmological constant problem.

Contribution

The paper introduces a new vector field model that cancels the cosmological constant without disrupting local Newtonian gravity, improving upon previous models.

Findings

Minkowski spacetime emerges as an attractor in the model

The model cancels arbitrary cosmological constants

Local gravitational physics remains unaffected

Abstract

Following an earlier suggestion by Dolgov, we present a specific model of two massless vector fields which dynamically cancel a cosmological constant of arbitrary magnitude and sign. Flat Minkowski spacetime appears asymptotically as an attractor of the field equations. Unlike the original model, the new model does not upset the local Newtonian gravitational dynamics.
