摘要

在这篇贡献中,我们回顾了一个一般的论点,表明如果引力子质量消失,扩展超引力的de Sitter临界点与磁弱引力猜想是紧张的。在此假设的激励下,我们回顾了引力子猜想,该猜想认为引力子质量消失的极限对于有效场论描述是病态的。最后,我们更一般地讨论了超重力中的德西特临界点(无质量引力子)的命运,并评论了这些工作沿着各个方向的扩展。这里展示的部分材料未发表。

De Sitter, gravitino mass and the swampland
In this contribution, we review a general argument showing that de Sitter critical points of extended supergravity are in tension with the magnetic weak gravity conjecture if the gravitino mass is vanishing. Motivated by this assumption, we review then the gravitino conjecture, which states that the limit of vanishing gravitino mass is pathological for the effective field theory description. Finally, we discuss more in general the fate of de Sitter critical points (with massless gravitini) in supergravity and comment on extensions of these works along various directions. Part of the material here presented is unpublished.
