Probing Lambda-DGP Braneworld Model
  In this article we study cosmic dynamics in the context of normal branch of DGP braneworld model. Using the current Planck data, we best fit the model and cosmological parameters in non-flat $\Lambda$DGP. With the transition redshift as a basic variable and statefinder parameters, our result shows that the Universe starts its accelerated expansion phase, slightly earlier than expected in $\Lambda$CDM cosmology. The result also alleviates the coincidence problem of the $\Lambda$CDM model.
