关于NS5-brane瞬子和体积稳定化

On NS5-brane instantons and volume stabilization

Hugo Looyestijn, Stefan Vandoren

摘要:

我们研究NS 5膜瞬子的一般方面的稳定的体积模量在Calabi-Yau紧化的II型字符串通量,和他们的orientifold版本。这些瞬子校正Kahler势,并且一般在弦耦合常数和体积的中间值处产生对标量势的显著贡献。在适当的条件下,它们产生令人振奋的条款,允许Meta稳定的德西特真空。

英文摘要:

We study general aspects of NS5-brane instantons in relation to the stabilization of the volume modulus in Calabi-Yau compactifications of type II strings with fluxes, and their orientifold versions. These instantons correct the Kahler potential and generically yield significant contributions to the scalar potential at intermediate values of string coupling constant and volume. Under suitable conditions they yield uplifting terms that allow for meta--stable de Sitter vacua.
