| 英文摘要 | In this paper, we use the result in [c.y. sun and d.h. zhang, arxiv:astro-ph/0510709] to calculate the non-gaussianity of the racetrack models in [j.j. blanco-pillado, et al., jhep 0411 (2004) 063; arxiv:hep-th/0406230] and [j.j. blanco-pillado, et al., arxiv:hep-th10603129]. the two models give different non-gaussianities. both of them are reasonable. however, we find that, for multi-field inflationary models with the non-trivial metric of the field space, the condition of the slow-roll cannot guarantee small non-gaussiani ties. |
