| 英文摘要 | In this paper we constrain the tilt of the spectrum of primordial gravitational waves from Background Imaging of Cosmic Extragalactic Polarization (BICEP2) data only. We find r = 0.21(-0.10)(+0.04) and n(t) = -0.06(-0.23) (+0.25) (at 68% C.L.) which implies that a scale-invariant primordial gravitational waves spectra is consistent with BICEP2 nicely. Our results provide evidence for supporting inflation model, and the alternative models, for example the ekpyrotic model which predicts n(t) = 2, are ruled out at high significance level. |
