Toward a gravitational network: Bridging metric-affine gravity and no-scale supergravity

TL;DR

This paper links metric-affine gravity models to no-scale supergravity, demonstrating that their inflationary properties are compatible, thereby expanding the set of viable models for cosmic inflation.

Contribution

It establishes a correspondence between metric-affine gravity and no-scale supergravity models, showing their shared inflationary behavior.

Findings

Inflationary behavior is preserved across the models.

The work broadens the landscape of inflation-compatible theories.

A new connection between gravity and supergravity models is demonstrated.

Abstract

We consider a class of models in the framework of metric-affine gravity and establish their correspondence to the bosonic sector of a class of no-scale supergravity models. The excellent inflationary behavior of the gravitational models considered is carried over to the corresponding supergravity ones, thus, enriching the landscape of inflation-compatible models.
