IIB矩阵模型中的弦耦合和相互作用

String coupling and interactions in type IIB matrix model

Yoshihisa Kitazawa, Satoshi Nagaoka

摘要:

研究了IIB矩阵模型中闭弦的相互作用。闭超弦的基本相互作用是通过两个相交弦的复合来实现的。在IIB矩阵模型中,利用二维非对易规范理论,在IR极限下研究了这种相互作用。通过对复合几率的估计,我们确定了IIB矩阵模型中的弦耦合g_s。我们确认我们的鉴定是一致的矩阵弦论。

英文摘要:

We investigate the interactions of closed strings in IIB matrix model. The basic interaction of the closed superstring is realized by the recombination of two intersecting strings. Such interaction is investigated in IIB matrix model via two dimensional noncommutative gauge theory in the IR limit. By estimating the probability of the recombination, we identify the string coupling g_s in IIB matrix model. We confirm that our identification is consistent with matrix string theory.
