在弦理论U-对偶性的指导下,利用向上提升的反D6膜,在STU模型中给出了IIA型弦理论中De Sitter真空的一种简单的类KKLT结构。在四维空间中,模型被简化为具有三个手性多重态(即S、T和U)以及一个表示反D6膜的幂零多重态的超重力。我们还简要讨论了一个具有七个模的推广。
A simple, KKLT-like construction of de Sitter vacua in type IIA string theory is presented in an STU model with guidance from string theory U-duality and with an up-lifting anti-D6-brane. In four dimensions the model is reduced to= 1 supergravity with three chiral multiplets, namely S, T and U, as well as one nilpotent multiplet representing the anti-D6-brane. We briefly discuss also a generalization with seven moduli.
