YFS Resummation for Future Lepton-Lepton Colliders in SHERPA

Krauss, Frank; Price, Alan; Schönherr, Marek

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 + → f f¯ and 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 + → ZH,, in YFS resummation including fixed-order improvements up to order α3L3.
