我们受Aref'eva-Faddeev-Slavnov（AFS）构造未戴森S矩阵的启发，通过在全纯相干态表示中引入Faddeev-Kulish修饰，构建了有质量量子电动力学（QED）中红外有限散射振幅的生成泛函；树阶下，该修饰生成泛函可约化为带修饰边界条件的AFS路径积分。
英文摘要
We construct a generating functional for infrared-finite scattering amplitudes in massive quantum electrodynamics (QED) by including Faddeev-Kulish dressings in a holomorphic coherent-state representation, in the spirit of the construction of Aref'eva-Faddeev-Slavnov (AFS) for the undressed Dyson S-matrix. At tree level, the dressed generating functional reduces to an AFS path integral with dressed boundary conditions.
