超对称双场论的几何探索

Exploring the geometry of supersymmetric double field theory

Daniel Butter

摘要:

在超空间中重新讨论了N=1超对称二重场论的几何。为了保持对挠张量的约束,O(D)x O(D)的局部切空间群必须扩展为包含一个更高维生成元的塔。其中包括洛伦兹群的不可约钩子表示中的生成器,它测量了自旋连接的移位对称性(或模糊性)。这种测量甚至在纯玻色子理论中也是可能的,在那里它导致洛伦兹曲率,其唯一的非零部分是物理部分:广义爱因斯坦张量和广义标量曲率。提出了一种与超Maxwell $_\infty$代数的关系。超空间Bianchi恒等式的求解一直到二维,并明确地(重新)导出了分量超对称变换和运动方程。

英文摘要:

The geometry of N=1 supersymmetric double field theory is revisited in superspace. In order to maintain the constraints on the torsion tensor, the local tangent space group of O(D) x O(D) must be expanded to include a tower of higher dimension generators. These include a generator in the irreducible hook representation of the Lorentz group, which gauges the shift symmetry (or ambiguity) of the spin connection. This gauging is possible even in the purely bosonic theory, where it leads to a Lorentz curvature whose only non-vanishing pieces are the physical ones: the generalized Einstein tensor and the generalized scalar curvature. A relation to the super-Maxwell$_\infty$ algebra is proposed. The superspace Bianchi identities are solved up through dimension two, and the component supersymmetry transformations and equations of motion are explicitly (re)derived.
