Complete one-loop corrections to e+ e- -> W+ W- in the MSSM

Abstract

The complete O(\alpha) corrections including soft-photon bremsstrahlung to the process e^+ e^- -> W^+ W^- in the MSSM are calculated for on-shell W bosons. The relative difference between the MSSM and Standard Model corrections is generally quite small. The maximum deviation from the Standard Model within the scanned region of parameter space is \lesssim 1.5% for unpolarized and transversally polarized W bosons, and \lesssim 2.7% for longitudinal W bosons.
