利用前一篇论文中发展的技术，计算了全息重整化群流描述的场理论中的三点函数。我们考虑一个由一个活动标量和一个惰性标量耦合到重力的系统。对于GPPZ流，它们的对偶算符创建的状态被解释为= 1 SYM理论的胶球，它位于重整化群流的红外端。计算了三个胶球过程的散射振幅，在= 1 SYM理论中对胶球衰变进行了精确的预测。包括低洼胶球的数值结果。
Using techniques developed in a previous paper three-point functions in field theories described by holographic renormalization group flows are computed. We consider a system of one active scalar and one inert scalar coupled to gravity. For the GPPZ flow, their dual operators create states that are interpreted as glueballs of the = 1 SYM theory, which lies at the infrared end of the renormalization group flow. The scattering amplitudes for three-glueball processes are calculated providing precise predictions for glueball decays in = 1 SYM theory. Numerical results for low-lying glueballs are included.
