M. Gunaydin, H. Samtleben, E. Sezgin

摘要:

幻方超引力是一类非常特殊的超引力理论,它在不同维度上的对称性和物质含量对应于弗赖登塔尔、罗森菲尔德和山雀幻方非凡几何的对称性和潜在的代数结构。这些对称群包括例外群和它们的一些特殊子群。在本文中,我们研究这些理论的一般规范在六维导致新的耦合之间的矢量场和张量场。我们表明,在超多重态耦合的情况下,规范群是唯一确定的一个最大的一组内的等距群SO(n_T,1)的张量多重态部门的交换平移。此外,我们发现,在一般的规范代数允许中心荷,可能有非平凡的作用在超多重态标量。我们确定了新的最小耦合,Yukawa耦合和标量势。

英文摘要:

Magical supergravities are a very special class of supergravity theories whose symmetries and matter content in various dimensions correspond to symmetries and underlying algebraic structures of the remarkable geometries of the Magic Square of Freudenthal, Rozenfeld and Tits. These symmetry groups include the exceptional groups and some of their special subgroups. In this paper, we study the general gaugings of these theories in six dimensions which lead to new couplings between vector and tensor fields. We show that in the absence of hypermultiplet couplings the gauge group is uniquely determined by a maximal set of commuting translations within the isometry group SO(n_T,1) of the tensor multiplet sector. Moreover, we find that in general the gauge algebra allows for central charges that may have nontrivial action on the hypermultiplet scalars. We determine the new minimal couplings, Yukawa couplings and the scalar potential.
