Prospects for Triple Gauge Coupling Measurements at Future Lepton Colliders and the 14 TeV LHC

Understand

The $WW$ production is the primary channel to directly probe the triple gauge couplings.

• We first analyze the $e^+ e^- \rightarrow W^+ W^-$ process at the future lepton collider, China's proposed Circular Electron-Positron Collider (CEPC).
• We use the five kinematical angles in this process to constrain the anomalous triple gauge couplings and relevant dimension six operators at the CEPC up to the order of magnitude of $10^{-4}$.
• The most sensible information is obtained from the distributions of the production scattering angle and the decay azimuthal angles.
