自相互作用基本弦与黑洞

Self-interacting fundamental strings and black holes

Diego Chialva

摘要:

我们研究了大质量密弦态的尺寸分布和典型的弦配置,因为一个缓慢增加的弦耦合,在零和非零的Neveu-Schwarz费用的情况下。计算是严格执行的弦论,从数量是明确定义的理论,因此澄清以前的工作就这个问题是基于各种近似技术。我们发现,从一个与黑洞对应原理预测的耦合值开始,弦系综在任何维度上都被其大小在对应的黑洞视界半径内的紧致态所支配,该视界半径在黑洞/弦跃迁点处的弦尺度的量级。

英文摘要:

We study the size distribution of very massive close string states and the typical string configuration as one slowly increase the string coupling, both in the case of zero and of non-zero Neveu-Schwarz charges. The computations are performed rigorously in string theory, starting from quantities that are well-defined in the theory and therefore clarify previous works on the subject which were based on various approximation techniques. We find that, starting from a value of the coupling in agreement with the one predicted by the black hole correspondence principle, the string ensemble is dominated in any dimensions by compact states whose size is within the correspondent black hole horizon radius, which is of the order of the string scale at the black hole/string transition point.
