N=4 SYM中有限大小场强算符的反常维数

Anomalous dimensions of finite size field strength operators in N=4 SYM

Matteo Beccaria, Valentina Forini

摘要:

在N=4的超Yang-Mills理论中,我们考虑纯胶子算符Tr(F^L)的高阶反常维数gamma_L(g),其中F是自对偶场强的一个分量.我们提出了紧凑的封闭表达式依赖于参数L,重现预测的贝特Anastrophic方程高达五个循环的顺序,包括超越敷料校正。随着微扰阶数的增加,尺寸依赖性遵循一个简单的模式,并暗示了这些特殊算子的隐藏关系。

英文摘要:

In the N=4 super Yang-Mills theory, we consider the higher order anomalous dimensions gamma_L(g) of purely gluonic operators Tr(F^L) where F is a component of the self-dual field strength. We propose compact closed expressions depending parametrically on L that reproduce the prediction of Bethe Ansatz equations up to five loop order, including transcendental dressing corrections. The size dependence follows a simple pattern as the perturbative order is increased and suggests hidden relations for these special operators.
