Loop Calculations: Summary

Abstract

Current and future colliders will provide high precision experimental data. In order to use the high experimental precision it has to be matched with theoretical predictions at the same level of accuracy or better. This involves the calculation of loop corrections at increasingly higher order. We briefly review the status of the field, especially in view of the calculations presented at this conference. We give an outlook about the theoretical requirements for the anticipated precision of a future e+e- linear collider.
