We consider vacuum solutions in M theory of the form of a five-dimensional Kaluza-Klein black hole cross T6. In a certain limit, these include the five-dimensional neutral rotating black hole (cross T6). From a type-IIA standpoint, these solutions carry D0 and D6 charges. We show that there is a simple D-brane description which precisely reproduces the Hawking-Bekenstein entropy in the extremal limit, even though supersymmetry is completely broken.
我们考虑M理论中五维卡鲁扎-克莱因黑洞与T6的乘积形式的真空解。在一定极限下，这些解包括五维中性旋转黑洞（与T6的乘积）。从IIA型理论的角度来看，这些解携带D0和D6电荷。我们表明，即使超对称性完全破缺，也存在一种简单的D膜描述，它能在极端极限下精确再现霍金-贝肯斯坦熵。
