关于六维和五维超引力的Pauli约化

On Pauli Reductions of Supergravities in Six and Five Dimensions

Arash Azizi, C. N. Pope

摘要:

在弯曲的内部空间(如球体)上的一般理论的降维不允许对包含等距群的杨-米尔斯规范玻色子的有限场集进行一致的截断。在极少数情况下,例如11维超引力的$S^7$约化,这种一致的“泡利约化”确实存在。在本文中,我们研究这个存在性问题的两个例子$S^2$减少超引力。我们这样做,利用某些$S^2$减少和组流形$S^3=SU(2)$减少的理论在一维更高的关系。由此证明了五维极小超引力不存在相容的$S^2$ Pauli约化。我们还表明,以前发现的一致泡利减少六维Salam-Sezgin超引力可以优雅地理解通过从七个维度的群流形减少。

英文摘要:

The dimensional reduction of a generic theory on a curved internal space such as a sphere does not admit a consistent truncation to a finite set of fields that includes the Yang-Mills gauge bosons of the isometry group. In rare cases, for example the $S^7$ reduction of eleven-dimensional supergravity, such a consistent "Pauli reduction" does exist. In this paper we study this existence question in two examples of $S^2$ reductions of supergravities. We do this by making use of a relation between certain $S^2$ reductions and group manifold $S^3=SU(2)$ reductions of a theory in one dimension higher. By this means we establish the non-existence of a consistent $S^2$ Pauli reduction of five-dimensional minimal supergravity. We also show that a previously-discovered consistent Pauli reduction of six-dimensional Salam-Sezgin supergravity can be elegantly understood via a group-manifold reduction from seven dimensions.
