## TL;DR

This paper explores a unique attractor behavior in a composite inflation model based on the gauged NJL framework, revealing a distinct inflationary attractor not present in fundamental scalar models, specifically aligning with the  attractor.

## Contribution

It identifies a novel inflationary attractor in the gauged NJL model, expanding the understanding of attractor structures beyond fundamental scalar inflation models.

## Key findings

- The gauged NJL model exhibits an  attractor in inflation.
- Composite inflation can have attractor structures absent in fundamental scalar models.
- The attractor corresponds to the  case in the -class of models.

## Abstract

We have investigated the attractor structure for the CMB fluctuations in composite inflation scenario within the gauged Nambu-Jona-Lasinio (NJL) model. Such composite inflation represents an attractor which can not be found in a fundamental scalar model. As is known, the number of inflationary models contains the attractor classified by the $\alpha$-attractor model. It is found that the attractor inflation in the gauged NJL model corresponds to the $\alpha = 2$ case.
