Abstract
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}e−e+→ff‾
and e^-e^+\to W^-W^+e−e+→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 ZHe−e+→ZH,
in YFS resummation including fixed-order improvements up to order
\alpha^3L^3α3L3.
