Triple Gauge Couplings at Future Hadron and Lepton Colliders

Abstract

The $WW$ production is the primary channel to directly probe the triple gauge couplings. We analyze the $e^{+}{e}^{-}\to W^{+}{W}^{-}$ process at the proposed Circular Electron-Positron Collider (CEPC), and find that the anomalous triple gauge couplings and relevant dimension six operators can be probed up to the order of $10^{-4}$. We also estimate constraints at the 14 TeV LHC, with both 300 fb${}^{-1}$ and 3000 fb${}^{-1}$ integrated luminosity from the leading lepton $p_T$ and azimuthal angle difference $\Delta {\varphi }_{ll}$ in the di-lepton channel. The constrain is somewhat weaker, up to the order of $10^{-3}$. The limits on the triple gauge couplings are complementary to those on the electroweak precision observables and Higgs couplings.
