不存在具有O8-planes的经典(反)de Sitter解

No classical (anti-)de Sitter solutions with O8-planes

Niccolò Cribiori, Daniel Junghans

摘要:

最近有人提出,IIA型弦论可能允许经典的德西特解决方案与O 8-平面作为唯一的本地化源。我们证明了这样的解与积分超引力运动方程不相容,类似于Maldacena和Nuñez的不通过定理。我们还详细讨论了分歧和不连续的O 8平面的位置,并认为他们不无效这样的论点。我们还表明,最近提出的一类非超对称AdS解决方案与O 8-平面是在对比,以及与我们的结果。

英文摘要:

It was recently proposed that type IIA string theory may allow classical de Sitter solutions with O8-planes as the only localized sources. We show that such solutions are incompatible with the integrated supergravity equations of motion, analogously to the no-go theorem due to Maldacena and Nuñez. We also discuss in detail divergences and discontinuities at the O8-plane positions and argue that they do not invalidate such an argument. We furthermore show that a recently proposed class of non-supersymmetric AdS solutions with O8-planes is in contrast with our results as well.
