Electroweak Radiative Corrections at High Energies

TL;DR

This paper reviews the emergence of large electroweak radiative corrections at energies well above the electroweak scale, focusing on logarithmic enhancements that grow with energy. It surveys explicit one-loop calculations, a universal one-loop framework, and explicit two-loop checks, and discusses resummation via exponentiation and infrared evolution methods. A key point is that, unlike QED/QCD, leading electroweak logs do not cancel in inclusive quantities, due to non-Abelian initial states, with important implications for precision predictions at TeV scales. The discussion highlights the practical relevance for future colliders and identifies areas where subleading and BN-violating effects require further study.

Abstract

For energies far above the electroweak scale, large electroweak radiative corrections occur that grow logarithmically with energy and can easily reach several tens of per cent in the TeV range. Recent work on these corrections is reviewed.
