平面N=4超Yang-Mills理论中长度不超过5的单圈阶标量算子的三点函数

Three-point functions in planar N=4 super Yang-Mills Theory for scalar operators up to length five at the one-loop order

George Georgiou, Valeria Gili, Andre Grossardt, Jan Plefka

摘要:

本文在单圈水平上对平面SU(N)N=4超杨-米尔斯理论中的三点函数进行了系统的微扰研究,其中涉及长度为5的标量场算符.为此,我们已经计算了40个结构常数的样本,涉及长度不超过5的主算子,这些主算子完全是从标量场构建的。本文提出了一种组合修整技术,将树级修整器提升为单回路修整器。此外,我们还解决了所涉及的算符的(g_YM)^2级的混合,这相当于与双费米子的混合,具有双导数插入以及标量扇区中的自混合贡献。这部作品取代了2010年两位作者的预印本,该预印本忽略了混合贡献。

英文摘要:

We report on a systematic perturbative study of three-point functions in planar SU(N) N=4 super Yang-Mills theory at the one-loop level involving scalar field operators up to length five. For this we have computed a sample of 40 structure constants involving primary operators of up to and including length five which are built entirely from scalar fields. A combinatorial dressing technique has been developed to promote tree-level correlators to one-loop level. In addition we have resolved the mixing up to the order (g_YM)^2 level of the operators involved, which amounts to mixings with bi-fermions, with bi-derivative insertions as well as self-mixing contributions in the scalar sector. This work supersedes a preprint by two of the authors from 2010 which had neglected the mixing contributions.
