M5-Branes的减少

Null Reductions of M5-Branes

Neil Lambert, Tristan Orchard

摘要:

我们执行一个时空的M5-膜,承认一个空的Killing矢量,包括耦合到背景4-形式的通量和可能的扭曲的正常束的一般减少。我们给出了这个作用量的非阿贝尔扩张,并给出了它的超对称变换。结果是一类4+1维的超对称非洛仑兹规范理论,它依赖于6维时空的几何。这些可以用于各种流形上约化的M5-膜的DLCQ构造。

英文摘要:

We perform a general reduction of an M5-brane on a spacetime that admits a null Killing vector, including couplings to background 4-form fluxes and possible twisting of the normal bundle. We give the non-abelian extension of this action and present its supersymmetry transformations. The result is a class of supersymmetric non-lorentzian gauge theories in 4+1 dimensions, which depend on the geometry of the six-dimensional spacetime. These can be used for DLCQ constructions of M5-branes reduced on various manifolds.
