摘要我们考虑四维黎曼自旋流形中的刚性超对称理论。我们从一开始就直接用欧几里得签名构建拉格朗日函数,跟踪潜在的边界项。我们将超对称的条件重新表述为适当 SU(2) 或平凡 G 结构的扭转类的一组条件。我们用许多例子来说明形式主义,包括具有非消失 Weyl 张量的超对称背景。
A bstractWe consider rigid supersymmetric theories in four-dimensional Riemannian spin manifolds. We build the Lagrangian directly in Euclidean signature from the outset, keeping track of potential boundary terms. We reformulate the conditions for supersymmetry as a set of conditions on the torsion classes of a suitable SU(2) or trivial G-structure. We illustrate the formalism with a number of examples including supersymmetric backgrounds with non-vanishing Weyl tensor.
