论文摘要
除了具有时空超对称性的熟悉的弦理论外，还有许多非对称的十维超级串。几乎所有这些理论都封闭了tachyons，表明对要进行量化的真空存在错误识别。在这项工作中，我们确定了所有已知速度型超弦的（元）稳定的真空吸尘器。这些真空都是较低的，其中大多数是熟悉的二维弦理论。但是，在尺寸6、8和9中也有有趣的解决方案的示例，分别具有$ e_7 \ times e_7 $，$ su（16）$和$ e_8 $。这些特殊的真空吸尘器具有正真空能，没有模量。
In addition to the familiar string theories with spacetime supersymmetry, there exist a number of non-supersymmetric ten-dimensional superstrings. Nearly all of these theories have closed string tachyons, indicating a misidentification of the vacuum around which they are to be quantized. In this work, we identify (meta)stable vacua for all known tachyonic superstrings. These vacua are all lower-dimensional, with most of them being familiar two-dimensional string theories. However, there are also intriguing examples of solutions in dimensions 6, 8, and 9, with respective gauge groups $E_7 \times E_7$, $SU(16)$, and $E_8$. These special vacua have positive vacuum energy and no moduli.
