论文摘要
我们计算了一个循环散射幅度,以用于任意数量的壳上纤维的阳性螺旋性和一个在准穆尔蒂恢复运动学中处理的脱壳胶状。结果是完全计量的不变性,并具有正确的壳上极限。我们的方法基于嵌入外壳过程,以及与辅助夸克或gluon线的更大的全壳过程中所需的贡献。
We calculate one loop scattering amplitudes for arbitrary number of positive helicity on-shell gluons and one off-shell gluon treated within the quasi-multi Regge kinematics. The result is fully gauge invariant and possesses the correct on-shell limit. Our method is based on embedding the off-shell process, together with contributions needed to retain gauge invariance, in a bigger fully on-shell process with auxiliary quark or gluon line.
