# Accelerating models with a hybrid scale factor in extended gravity

## TL;DR

This paper explores a cosmological model using a hybrid scale factor in extended gravity, demonstrating its near-constant behavior similar to a cosmological constant over significant cosmic times.

## Contribution

It introduces a simplified approach to model cosmic transit in extended gravity using a hybrid scale factor, with analysis of its viability and scalar field reconstruction.

## Key findings

- Model mimics cosmological constant for large cosmic times
- Deceleration parameter indicates cosmic acceleration
- Model remains viable under diagnostic tests

## Abstract

Dynamical aspects of cosmological model in an extended gravity theory have been investigated in the present work. We have adopted a simplified approach to obtain cosmic features, which in fact requires more involved calculations. A cosmological model is constructed using a hybrid scale factor that simulates a cosmic transit behaviour. The deceleration parameter and energy conditions have been obtained for the constructed model. Scalar fields have been reconstructed from the present model in the extended gravity. Different diagnostic methods have been applied to analyse the viability of the constructed model. The present model almost looks like a cosmological constant for a substantial cosmic time zone and does not show any slowing down feature in near future.
