YFS Resummation for Future Lepton-Lepton Colliders in SHERPA
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...

| description | 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
$\alpha^3L^3$. |
