摘要

作为AdS/CFT对应的结果,平面N=4{\cal N} =4超Yang-Mills SU(N)理论预期表现出弦论行为和多Regge渐近性。本文扩展了我们近期的研究,考虑解析性问题,这是Regge渐近性的核心特征。我们将平面极限下的平坦空间开弦理论与N=4{\cal N}=4超Yang-Mills理论进行对比,后者由Bern、Dixon和Smirnov \cite{Bern:2005iz} (BDS)关于n胶子散射的猜想表示,该猜想被认为对n=4,5n=4,5是精确的,而对n6n\geq 6仅由一个交叉比函数修正。需要强调的是,多Regge分解应应用于具有确定符号的轨迹。平坦空间弦理论中实现的各种解析性和分解约束,至少当指数因子在红外调节器中截断到O(ϵ)O(\epsilon)以下时,BDS猜想并不满足。
