Relaxation of the cosmological constant at inflation?

TL;DR

This paper proposes a mechanism where the cosmological constant is relaxed to its current small value during inflation, involving a low-scale, long-duration, and unconventional inflationary process.

Contribution

It introduces a novel mechanism for relaxing the cosmological constant during inflation, differing from traditional models.

Findings

Cosmological constant can be relaxed during inflation.

Requires low-scale, long-duration inflation.

Proposes an unconventional inflationary source.

Abstract

We suggest that the cosmological constant has been relaxed to its present, very small value during the inflationary stage of the evolution of the Universe. This requires relatively low scale, very long duration and unconventional source of inflation. We present a concrete mechanism of the cosmological constant relaxation at the inflationary epoch.
