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

摘要： 我们研究在具有极化电子束的直线对撞机上轻子产生过程的辐射修正。 我们计算了由于三族夸克和超夸克引起的极化电子束的一环修正截面，在$\bar{MS}$方案中进行，扩展了我们之前仅考虑第三族夸克和超夸克的一环修正的非极化截面计算。 在某些情况下，我们发现对树级截面有相当大的修正。 例如，对于右旋极化电子和较大的$\tan \beta$情况，修正可以达到30%，从而能够对超夸克质量参数敏感。 显示英文摘要

摘要： 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 $\bar{MS}$ 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.
