超对称畴壁

Supersymmetric Domain Walls

Eric A. Bergshoeff, Axel Kleinschmidt, Fabio Riccioni

摘要:

我们分类的半超对称的“域壁”,即膜的余维1,在环面紧IIA/IIB弦论,并显示这些域壁属于哪个规范超引力理论。我们使用超对称Wess-Zumino项的要求,E11卡茨-穆迪代数的性质和嵌入张量形式作为输入。我们证明了半超对称畴壁的数目是超对称代数中相应中心荷数目的倍数,其中多重数与BPS条件的简并度有关.

英文摘要:

We classify the half-supersymmetric "domain walls", i.e. branes of codimension one, in toroidally compactified IIA/IIB string theory and show to which gauged supergravity theory each of these domain walls belong. We use as input the requirement of supersymmetric Wess-Zumino terms, the properties of the E11 Kac-Moody algebra and the embedding tensor formalism. We show that the number of half-supersymmetric domain walls is a multiple of the number of corresponding central charges in the supersymmetry algebra, where the multiplicity is related to the degeneracy of the BPS conditions.
