SUSY Loop Contributions to the $W$ -Pair Production in $e^{+} e^{-}$ Collisions

Kaoru Hagiwara, Shinya Kanemura, Yoshiaki Umeda

We discuss one-loop contributions of supersymmetry (SUSY) particles to the process $e^{+} e^{-} \to W^{+} W^{-}$ in the minimal supersymmetric standard model. The calculation is tested by us…

One-loop contributions of charginos and neutralinos to W+ W- production in e+ e- collisions

Kaoru Hagiwara, Shinya Kanemura, Yoshiaki Umeda

We study one-loop effects of charginos and neutralinos on the helicity amplitudes for the process $e^{+} e^{-} \to W^{+} W^{-}$ in the MSSM. The calculation is tested by using two methods. Fi…
