Description
We investigate the effect of the bulk content in the general Gauss-Bonnet braneworld on the evolution of the Universe. We find that the Gauss-Bonnet term and the combination of the dark radiation and the matter content of the bulk play a crucial role in the Universe's evolution. We show that our model can describe the superacceleration of our Universe with the equation of state of the effective dark energy in agreement with observations
