超引力和稀薄成因中新的D项混沌暴胀

New D-term chaotic inflation in supergravity and leptogenesis

Kenji Kadota, Teruhiko Kawano, Masahide Yamaguchi

摘要:

提出了一个新的超引力D项主导的混沌暴胀模型。这个模型中的F平坦方向被占主导地位的D项提升,这导致了混乱的暴胀和随后的再加热。暴胀后没有宇宙弦形成,因为U(1)规范对称性在暴胀期间被破坏。通过我们的D-项混沌暴胀方案中的暴胀子衰变的leptogenesis方案进行了讨论。

英文摘要:

We present a new model of D-term dominated chaotic inflation in supergravity. The F-flat direction present in this model is lifted by the dominant D-term, which leads to chaotic inflation and subsequent reheating. No cosmic string is formed after inflation because the U(1) gauge symmetry is broken during inflation. The leptogenesis scenario via the inflaton decay in our D-term chaotic inflation scenario is also discussed.
