Orbifold上的膜

Membranes on an Orbifold

Neil Lambert, David Tong

摘要:

我们收获的线索,以帮助解释最近发现的N=8超对称陈-西蒙斯理论与SO(4)规范对称性。该理论被认为是描述两个膜运动的orbifold R8/Z2。在k=1和k=2水平上,经典模空间M分别与SO(4)和SO(5)超Yang-Mills理论的红外模空间重合.对于更高的Chern-Simons水平,模空间是M的商.在模空间中的一般点处,质量谱正比于由两个膜和轨道不动点形成的三角形的面积。

英文摘要:

We harvest clues to aid with the interpretation of the recently discovered N=8 supersymmetric Chern-Simons theory with SO(4) gauge symmetry. The theory is argued to describe two membranes moving in the orbifold R8/Z2. At level k=1 and k=2, the classical moduli space M coincides with the infra-red moduli space of SO(4) and SO(5) super Yang-Mills theory respectively. For higher Chern-Simons level, the moduli space is a quotient of M. At a generic point in the moduli space, the massive spectrum is proportional to the area of the triangle formed by the two membranes and the orbifold fixed point.
