摘要： $\alpha'$修正了大时空维数下史瓦西黑洞的近地平线动力学，$D$受控于由雪茄共形场论（CFT）以及地平面上球面上的经典sigma模型组成的弦世界面理论，连同中心电荷为$26-D$的类时Liouville理论。 在弱弦耦合的主阶上，黑洞热力学对类时Liouville理论的细节不敏感。 在此极限下，我们使用了[arxiv: 2310.02313]中基于Lewkowycz-Maldacena技巧的无穷小偏离规范的闭弦世界面形式化方法，在$\alpha'$中精确计算热熵。 在$\alpha'\to 0$极限下的主要项和我们的结果的第一个弦修正与目标空间的Callan-Myers-Perry公式完全一致。 显示英文摘要

摘要： $\alpha'$ corrections to near-horizon dynamics of a Schwarzschild black hole in a large number of spacetime dimensions $D$ are governed by the worldsheet theory composed of the cigar CFT and the classical sigma model on the sphere at the horizon, along with a timelike-Liouville theory of central charge $26-D$. At leading order in weak string coupling, blackhole thermodynamics is insensitive to the details of timelike Liouville theory. In this limit, we use Lewkowycz-Maldacena-trick motivated infinitesimally off-shell closed string worldsheet formalism in [arxiv: 2310.02313] to calculate thermal entropy exactly in $\alpha'$. The leading term in $\alpha'\to 0$ limit and the first stringy correction of our result are in precise agreement with the target space Callan-Myers-Perry formula.
