在AdS{sub 5}{times} S{sup 5}的各种轨道上,提出并验证了N=2、thinsp1、thinsp0(超)共形不变量的四维量子场论(QFTs)与IIB型弦理论的对应关系。这允许我们将寻找稳定的非平凡非超对称弦背景的问题转化为实现膜上的非平凡重整化群不动点qft的问题。在这种情况下,RG固定线对应于弦理论,在弦理论中,真空能量不是量子力学产生的。{版权所有}{ital 1998} {ital美国物理学会
We propose and test correspondences between 4D quantum field theories (QFTs) with N=2,thinsp1,thinsp0 (super)conformal invariance and type IIB string theory on various orbifolds of AdS{sub 5}{times} S{sup 5} . This allows us to translate the problem of finding stable nontrivial nonsupersymmetric string backgrounds into the problem of realizing nontrivial renormalization group (RG) fixed point QFTs on branes. RG fixed lines in this context correspond to string theories in which no vacuum energy is generated quantum mechanically. {copyright} {ital 1998} {ital The American Physical Society}
