论文摘要
我们为特定的$ n $ -gluon两个环散射部分振幅提供了明确的表达。具体而言,我们为单个痕迹$ n_c $独立颜色部分振幅提供了一种分析形式,以使所有外部振荡都具有正螺旋。
We present an explicit expression for a particular $n$-gluon two loop scattering partial amplitude. Specifically we present an analytic form for the single trace $N_c$ independent colour partial amplitude for the case where all external gluons have positive helicity.
