Radiative Corrections for the LHC and Linear Collider Era

We emphasize the importance of including radiative corrections when extracting physics from colliders such as the Tevatron Run II at Fermilab, the Large Hadron Collider (LHC) at CERN, and a future linear collider (LC). We review both well-tested methods and recent advances for calculating these corrections within the Standard Model of electroweak and strong interactions. We discuss the demands on theory and the prospects for matching or exceeding the anticipated experimental precision.
