Radiative Corrections to Chargino Production in Electron-Positron Collisions with Polarised Beams

Abstract

We study radiative corrections to chargino production at linear colliders with polarised electron beams. We calculate the one-loop corrected cross-sections for polarised electon beams due to three families of quarks and squarks, working in the $\overline{MS}$ scheme, extending our previous calculation of the unpolarised cross-section with one-loop corrections due to the third family of quarks and squarks. In some cases we find rather large corrections to the tree-level cross-sections. For example for the case of right-handed polarised electrons and large $\tan \beta$ the corrections can be of order 30%, allowing sensitivity to the squark mass parameters.
