英文摘要We update the constraints on the power spectra of primordial curvature perturbation and tensor perturbation including Planck data 2015 (P15) and recently released BICEP2/Keck data (BK15), Baryon Acoustic Oscillation data and the Type Ia supernovae data. We find that the upper limits of tensor-to-scalar ratio are 0.061, 0.064 and 0.072 at 95% confidence level (CL) in the Lambda CDM+r, Lambda CDM+r+alpha(s) and Lambda CDM+r+alpha(s)+beta(s) models respectively, where alpha(s) and beta(s) are the running of scalar spectral index and running of running. The inflation model with a concave potential is favored at more than 95% CL. In addition, parametrizing the slow-roll parameter epsilon similar to 1/N-p, where N is the e-folding number before the end of inflation and taken in the range of [50, 60] and [14, 75] respectively, we conclude that the inflation model with a monomial potential V(phi) similar to phi(n) is disfavored at more than 95% CL, and both the Starobinsky inflation model and brane inflation model are still consistent with the data.
