论文摘要
我们提出了Yennie-\ - frautschi-\ -suura（YFS）方案的实现，以通过在对未来Lepton Collider至关重要的过程中排放柔软的真实和虚拟光子来对对数进行全面重新召集。它们包括$ e^-e^+\ to f \ bar {f} $和$ e^-e^+\ to w^-w^+$，我们在其中验证了实施结果，并通过固定排名进行了改进，并从最精确的计算中获得。我们还首次向higgs-strahlungs进程的结果显示，$ e^-e^+\ to zh $，包括YFS重新召集，包括固定订单改进，直至$α^3l^3 $。
We present an implementation of the Yennie--\-Frautschi--\-Suura (YFS) scheme for the all-orders resummation of logarithms from the emission of soft real and virtual photons in processes that are critical for future lepton colliders. They include, in particular, $e^-e^+\to f\bar{f}$ and $e^-e^+\to W^-W^+$, where we validate the results of our implementation, improved with fixed-order corrections, with those obtained from the most precise calculations. We also show, for the first time, results for the Higgs-Strahlungs process, $e^-e^+\to ZH$, in YFS resummation including fixed-order improvements up to order $α^3L^3$.
