The Cosmology of Asymmetric Brane Modified Gravity
arXiv:0904.4182 · doi:10.1088/1475-7516/2009/09/020
Abstract
We consider the asymmetric branes model of modified gravity, which can produce late time acceleration of the universe and compare the cosmology of this model to the standard $Î$CDM model and to the DGP braneworld model. We show how the asymmetric cosmology at relevant physical scales can be regarded as a one-parameter extension of the DGP model, and investigate the effect of this additional parameter on the expansion history of the universe.
