AbstractWe study the inflation scenario with the nonminimally derivative coupling XR(3), where X = del(mu)phi del(mu)phi, phi is the inflaton and R-(3) is the three-dimensional intrinsic Ricci scalar on the spacelike hypersurface, and analytically calculate the corrections of XR(3) on the power spectra of primordial perturbations. It is found that, for the phi(2) inflation model, the corresponding predictions can be driven to the best-fit region of the n(s)-r diagram.
