膜缺损

Defect Branes

E. Bergshoeff, T. Ortin, F. Riccioni

摘要:

本文讨论了(环面紧化)IIA/IIB弦论中的“缺陷膜”,即余维为2的膜的一些一般性质.特别地,我们给出了2 < D < 11维超对称亏损膜的完整分类,以及它们作为膜和一组“广义”Kaluza-Klein单极子的高维弦和M-理论起源。指出了广义Kaluza-Klein解与一类特殊的混合对称张量之间的关系。这些混合对称张量可以在线性化的水平上定义为描述传播自由度的超引力势的近似。在超对称代数中,超对称亏损膜的数目总是相应的中心荷数目的两倍。

英文摘要:

We discuss some general properties of "defect branes", i.e. branes of co-dimension two, in (toroidally compactified) IIA/IIB string theory. In particular, we give a full classification of the supersymmetric defect branes in dimensions 2 < D < 11 as well as their higher-dimensionalstring and M-theory origin as branes and a set of "generalized" Kaluza-Klein monopoles. We point out a relation between the generalized Kaluza-Klein monopole solutions and a particular type of mixed-symmetry tensors. These mixed-symmetry tensors can be defined at the linearized level as duals of the supergravity potentials that describe propagating degrees of freedom. It is noted that the number of supersymmetric defect branes is always twice the number of corresponding central charges in the supersymmetry algebra.
