论文摘要
我们描述了将量子场理论的\ textit {Worldline形式主义}应用于由$ n $ photons打扮的\ textit {Worldline形式主义}来研究多线性康普顿散射过程,从而解释了这种方法如何(其计算优势)如何以多环的订单众所周知 - 收益紧凑和表现范围的散射态度散射。
We describe progress applying the \textit{Worldline Formalism} of quantum field theory to the fermion propagator dressed by $N$-photons to study multi-linear Compton scattering processes, explaining how this approach -- whose calculational advantages are well-known at multi-loop order -- yields compact and manifestly gauge invariant scattering amplitudes.
