非交换D-膜、开弦和规范理论

Nonabelian D-branes, Open Strings, and Gauge Theory

Charles B. Thorn

摘要:

在临界闭弦论中,由原来的对偶共振模型所确定的开弦动力学与由D-膜结构所确定的开弦动力学之间存在着细微的差别。例如,与前者相反,后者除了共有的无质量胶子外,还有无质量标量。我们介绍和解释的概念nonabelian D膜,阐明了这一区别。我们利用这个概念为大N量子色动力学(纯杨-米尔斯规范理论)的弦理论提供了新的可能性。

英文摘要:

There is a subtle difference between the open string dynamics determined by the original dual resonance models and that determined by D-brane constructions within critical closed string theory. For instance, in contrast to the former, the latter have massless scalars in addition to the massless gluon shared by both. We introduce and explain the concept of nonabelian D-branes which illuminates this distinction. We employ this concept to offer new possibilities for string duals for large N QCD (pure Yang-Mills gauge theory).
