Observational consequences of a dark interaction model

TL;DR

This paper investigates a cosmological model where dark energy decays into dark matter, analyzing its impact on universe expansion, luminosity distance, acoustic oscillations, and statefinder parameters.

Contribution

It introduces a decay model of dark energy into dark matter and explores its observational consequences on cosmic evolution.

Findings

Identifies the transition redshift where universe expansion dynamics change.

Analyzes effects on luminosity distance and acoustic oscillations.

Discusses modifications to statefinder parameters.

Abstract

We study a model with decay of dark energy and creation of the dark matter particles. We integrate the field equations and find the transition redshift where the evolution process of the universe change the accelerated expansion, and discuss the luminosity distance, acoustic oscillations and the statefinder parameters.
