Brane cosmology from observational surveys and its comparison with standard FRW cosmology

Abstract

Several simple dark energy models on the brane are investigated. They are compared with corresponding models in the frame of 4d Friedmann-Robertson-Walker cosmology. For constraining the parameters of the models considered, recent observational data, including SNIa ap- parent magnitude measurements, baryon acoustic oscillation results, Hubble parameter evolution data and matter den- sity perturbations are used. Also, explicit formulas of the so-called state-finder parameters in teleparallel theories are found that could be useful to test these models and com- pare Loop Quantum Cosmology and Brane Cosmology. The conclusion is reached that a joint analysis as the one devel- oped here allows to estimate, in a very clear way, possible deviation of our cosmology from the standard Friedmann- Robertson-Walker one
