Observational constrains on the DGP brane-world model with a Gauss-Bonnet term in the bulk

TL;DR

This paper evaluates the DGP brane-world model with a Gauss-Bonnet term using supernova, BAO, and H(z) data, finding it a viable explanation for cosmic acceleration.

Contribution

It provides the first comprehensive observational constraints on the DGP model with a Gauss-Bonnet term in the bulk.

Findings

Gauss-Bonnet-Induced Gravity model fits observational data well

Model can explain the universe's accelerated expansion

Parameters are consistent with current cosmological observations

Abstract

Using the data coming from the new 182 Gold type Ia supernova samples, the baryon acoustic oscillation measurement from the Sloan Digital Sky Survey and the H(z) data, we have performed a statistical joint analysis of the DGP brane-world model with a high curvature Gauss-Bonnet term in the bulk. Consistent parameters estimations show that the Gauss-Bonnet-Induced Gravity model is a viable candidate to explain the observed acceleration of our universe.
