| 英文摘要 | Recent analysis of the WMAP three-year data suggests f(NL)(local) NL similar or equal to 86.8 in the WMAP convention. It is necessary to make sure whether general single. field inflation can produce a large positive fNL before turning to other scenarios. We give some examples to generate a large positive f(NL)(equil) in general single inflation. Our models are different from ghost inflation. Due to the appearance of non-conventional kinetic terms, f(NL)(equil) NL >> 1 can be realized in single. eld inflation. |
