标题： Tachyon Splits the (d = 2 String) Black Hole Horizon and Turns it Singular

摘要： 我们给出了一个静态解，适用于包含快子$T$但不含其势能$V(T)$的$d = 2$临界弦理论。 这一解因此包含了快子的反作用，并且当$T = 0$时，退化为黑洞解。 当$T \neq 0$时，发现以下两点：(1) 上述黑洞的史瓦西视界分裂为两个，类似于雷斯勒-诺德斯特姆视界；(2) 曲率标量在视界处发展出新的奇异性。 正如我们所论证的，即使存在$V(T)$，这些特性也将持续存在。 讨论了一些可能消除这些奇点的方法。 显示英文摘要

摘要： We present a static solution for $d = 2$ critical string theory including the tachyon $T$ but not its potential $V(T)$. This solution thus incorporates tachyon back reaction and, when $T = 0$, reduces to the black hole solution. When $T \neq 0$ one finds that (1) the Schwarzschild horizon of the above black hole splits into two, resembling Reissner-Nordstrom horizons and (2) the curvature scalar develops new singularities at the horizons. These features, as we argue, will persist even with $V(T)$ present. Some possible methods for removing these singularities are discussed.
