Using the harmonic superspace formalism, we find the metric of a certain 8-dimensional manifold. This manifold is not compact and represents an 8-dimensional generalization of the Taub-NUT manifold. Our conjecture is that the metric that we derived is equivalent to the known metric possessing a discrete $Z_2$ isometry, which may be obtained from the metric describing the dynamics of four BPS monopoles by Hamiltonian reduction.

谐波超空间形式主义中的八维 Taub-NUT 类超 Kähler 度量

使用调和超空间形式，我们找到某个 8 维流形的度量。这个流形并不紧凑，代表了 Taub-NUT 流形的 8 维泛化。我们的猜想是，我们推导出的度量等价于具有离散 $Z_2$ 等距的已知度量，这可以从描述四个 BPS 单极子动力学的度量中获得，通过哈密顿量减少。
