Abstract
As an extension of Dvali-Gabadadze-Porrati (DGP) model, the Galileon theory has been proposed to explain the "self-accelerating problem" and "ghost instability problem". In this Paper, we extend the Galileon theory by considering a non-minimally coupled Galileon scalar with gravity. The statefinder analysis, diagnostic and constraint the model parameters have been investigate , we find , (at the confidence level) with . Further we show that due to the SNe Ia + BAO data ,our model behaves like a phantom-like dark energy.
