我们考虑了余维2膜存在下的六维Salam-Sezgin超引力。在这种情况下，膜只携带张力，我们提供了一种方法，通过添加适当的本地化Fayet-Iliopoulos条款，并相应地修改超对称变换超对称。由此产生的膜作用量具有N = 1超对称性（SUSY）。我们发现系统的轴对称真空，并表明，一个unwarp的背景解决方案与“足球”形的额外的维度，总是尊重N = 1超对称，与非超对称膜行动的背景。最后，我们一般发现多个零模的引力子在这种背景下，并讨论如何可以获得一个单一的手征零模存在于低能谱。
We consider the six-dimensional Salam-Sezgin supergravity in the presence of codimension-2 branes. In the case that the branes carry only tension, we provide a way to supersymmetrise them by adding appropriate localised Fayet-Iliopoulos terms and modifying accordingly the supersymmetry transformations. The resulting brane action has N = 1 supersymmetry (SUSY). We find the axisymmetric vacua of the system and show that one has unwarped background solutions with "football" -shaped extra dimensions which always respect N = 1 SUSY, in contrast with the non-supersymmetric brane action background. Finally, we generically find multiple zero modes of the gravitino in this background and discuss how one could obtain a single chiral zero mode present in the low energy spectrum.
