Electroweak Gauge Theories and Alternative Theories at a Future Linear e+e- Collider

TL;DR

This paper reviews studies on how a future linear e+e- collider can test the Standard Model and explore new physics through electroweak processes, highlighting findings from ECFA/DESY workshops beyond TESLA TDR.

Contribution

It provides a comprehensive review of potential measurements and sensitivities at a future linear collider, emphasizing previously unconsidered studies from ECFA/DESY workshops.

Findings

Linear colliders can test Standard Model processes with high precision.

They are sensitive to new physics via loop effects and interference.

The review highlights additional studies not included in TESLA TDR.

Abstract

The measurement of Standard Model processes tests the validity of the model at a given scale and is simultaneously sensitive to new physics through loop effects or interference with the Standard Model amplitudes. A variety of studies has been done to see what a linear collider in the energy range MZ < sqrt{s} < 1 TeV can offer. The work that has been done within the ECFA/DESY workshop on linear colliders is reviewed, especially what was not included in the TESLA TDR.
