论文摘要
在弦理论中，一个重要的挑战是证明是否可以通过完整的$α^{\ prime} $校正来平滑黑洞的奇异性。最简单的情况是考虑一个2D字符串黑洞或3D黑色字符串。该问题是在一个测量的Wess-Zumino-witten（WZW）模型中讨论的，结果应该对$α^{\ prime} $校正中的所有订单正确。基于最近对所有$α^{\ prime} $校正分类的显着进展，在这项工作中，我们通过低能效率的时空动作重新研究了这个问题，并通过完整的$α^{\ prime} $更正提供了2D黑洞的确切非扰动和非扰动解决方案。
In string theory, an important challenge is to show if the singularity of black holes can be smoothed out by the complete $α^{\prime}$ corrections. The simplest case is to consider a 2D string black hole or 3D black string. This problem was discussed in a gauged Wess-Zumino-Witten (WZW) model and the results are supposed to be correct to all orders in $α^{\prime}$ corrections. Based on the recent remarkable progress on classifying all the $α^{\prime}$ corrections, in this work, we re-study this problem with the low energy effective spacetime action, and provide classes of exact non-perturbative and non-singular solutions of the 2D black hole via complete $α^{\prime}$ corrections.
