| 英文摘要 | We locally reconstruct the inflationary potential by using the current constraints on r and n(s) from BICEP2 data. Assuming small and negligible alpha(s), the inflationary potential is approximately linear in Delta phi similar to M-pl range but becomes non-linear in Delta phi similar to 10M(pl) range. However if we vary the value of alpha(s) within the range given by constraints from Planck measurement, the local reconstruction is only valid in the range of Delta phi similar to 0.4M(pl), which challenges the inflationary background from the point of view of effective field theory. We show that, within the range of Delta phi similar to 0.4M(pl), the inflation potential can be precisely reconstructed. With the current reconstruction, we show that V(phi) similar to phi(2) and phi(3) are consistent, while phi model is ruled out by 95% confidence level of the reconstructed range of potential. This sets up a strong limit of large-field inflation models. |
