规范超引力、张量体系和M理论

Gauged Supergravities, Tensor Hierarchies, and M-Theory

Bernard de Wit, Hermann Nicolai, Henning Samtleben

摘要:

通过测量对偶群的非阿贝尔子群而引起的最大超引力理论的变形揭示了带电M理论自由度的存在,这些自由度不一定包含在超引力中。与M-理论自由度的关系由规范荷对偶群下的表象赋值以及随之而来的矢量和张量规范场所证实。这些规范场的底层层次结构是一般规范的一致性所必需的。作为一个例子,在三个时空维度的规范最大超引力是在一个版本中,所有可能的张量场出现。

英文摘要:

Deformations of maximal supergravity theories induced by gauging non-abelian subgroups of the duality group reveal the presence of charged M-theory degrees of freedom that are not necessarily contained in supergravity. The relation with M-theory degrees of freedom is confirmed by the representation assignments under the duality group of the gauge charges and the ensuing vector and tensor gauge fields. The underlying hierarchy of these gauge fields is required for consistency of general gaugings. As an example gauged maximal supergravity in three space-time dimensions is presented in a version where all possible tensor fields appear.
