小弦与T-对偶

Little strings and T-duality

Jungmin Kim, Seok Kim, Kimyeong Lee

摘要:

本文研究了Ⅱ型NS 5-膜上2dN = 4的小弦的规范理论描述。N个NS 5-膜上的IIB弦由N =(4,4)规范理论描述,U(N)瞬子模空间上的Higgs分支CFTs是相关的. IIA弦由N =(4,4)循环A_{N-1}理论描述,其库仑分支CFTs是相关的.我们研究了IIA弦的新的N =(0,4)π规范理论,这使得研究某些红外观测量变得容易。特别是,我们表明,椭圆属IIA / IIB字符串精确映射到对方的T-对偶。

英文摘要:

We study the 2d N = 4 gauge theory descriptions of little strings on type II NS5- branes. The IIB strings on N NS5-branes are described by the N = (4,4) gauge theories, whose Higgs branch CFTs on U(N) instanton moduli spaces are relevant. The IIA strings are described by N = (4,4) circular A_{N-1} quiver theories, whose Coulomb branch CFTs are relevant. We study new N = (0,4) quiver gauge theories for the IIA strings, which make it easier to study some infrared observables. In particular, we show that the elliptic genera of the IIA / IIB strings precisely map to each other by T-duality.
