论文摘要
在巨大的矢量超强中，带有充气（Scalaron）和Goldstino的最小Starobinsky超级重力与diLaton轴手性超级场合耦合，具有NOCALEKähler的潜力和超级能力。在膨胀期间，使用恒定项的kachru-kallosh-linde-trivei（KKLT）型机制，以稳定dialaton/axion，并证明会导致不稳定。通过添加替代的fayet-iliopoulos（FI）术语来治愈不稳定性，该术语不会导致$ r $ symmetry。在FI项的存在下，还研究了基于Wess-Zumino（WZ）型超电势的其他稳定机制。也简要讨论了与D3-Brane的可能联系。
The minimal Starobinsky supergravity with the inflaton (scalaron) and the goldstino in a massive vector supermultiplet is coupled to the dilaton-axion chiral superfield with the no-scale Kähler potential and a superpotential. The Kachru-Kallosh-Linde-Trivedi (KKLT)-type mechanism in the presence of a constant term in the superpotential is applied to stabilize the dilaton/axion during inflation, and it is shown to lead to an instability. The instability is cured by adding the alternative Fayet-Iliopoulos (FI) term that does not lead to the gauged $R$-symmetry. Other stabilization mechanisms, based on the Wess-Zumino (WZ)-type superpotential, are also studied in the presence of the FI term. A possible connection to a D3-brane is briefly discussed too.
