Abstract

Recent analysis of the WMAP three-year data suggests in the WMAP convention. It is necessary to make sure whether general single field inflation can produce a large positive f_NL before turning to other scenarios. We give some examples to generate a large positive f_NL ^equil in general single field inflation. Our models are different from ghost inflation. Due to the appearance of non-conventional kinetic terms, can be realized in single field inflation.
