半对称超空间上的弦

Strings on Semisymmetric Superspaces

K. Zarembo

摘要:

几个弦背景中出现的AdS/CFT对应描述的可积σ模型。它们的目标空间总是一个Z(4)超陪集(一个半对称超空间)。本文列出了微扰论中所有β函数为零且中心荷c<=26的半对称陪集。

英文摘要:

Several string backgrounds which arise in the AdS/CFT correspondence are described by integrable sigma-models. Their target space is always a Z(4) supercoset (a semi-symmetric superspace). Here we list all semi-symmetric cosets which have zero beta function and central charge c<=26 at one loop in perturbation theory.
