Model-independent limits for anomalous triple gauge bosons $W^{+}{W}^{-}\gamma$ coupling at the CLIC

Abstract

We investigate the potential of the Compact Linear Collider (CLIC) to probe the anomalous $W^{+}{W}^{-}\gamma$ coupling in $\gamma \gamma$, $\gamma {\gamma }^{\ast }$ and ${\gamma }^{\ast }{\gamma }^{\ast }$ collisions through the processes $\gamma \gamma \to W^{+}{W}^{-}$, $e^{+}\gamma \to e^{+}{\gamma }^{\ast }\gamma \to e^{+}{W}^{-}{W}^{+}$ and $e^{+}{e}^{-}\to e^{+}{\gamma }^{\ast }{\gamma }^{\ast }{e}^{-}\to e^{+}{W}^{-}{W}^{+}{e}^{-}$. We perform leptonic, semi-leptonic and hadronic decays channels for $W^{+}{W}^{-}$ production in the final state. Taking $\mathcal{L}=1\mathrm{a}{\mathrm{b}}^{-1}@\sqrt{s}=0.380\mathrm{TeV}$, $\mathcal{L}=2.5\mathrm{a}{\mathrm{b}}^{-1}@\sqrt{s}=1.5\mathrm{TeV}$ and $\mathcal{L}=5\mathrm{a}{\mathrm{b}}^{-1}@\sqrt{s}=3\mathrm{TeV}$, based on future CLIC data, the limits for $\Delta {\kappa }_{\gamma }$ and ${\lambda }_{\gamma }$ might reach up to $\mathcal{O}(10^{-5}-10^{-4})$ level in the most ideal with 5\hspace{0.8mm}$\mathrm{a}{\mathrm{b}}^{-1}$ set data, which shows a potential advantage compared to those from LHC, Tevatron and LEP data. Thus, our results represent that the processes $\gamma \gamma \to W^{+}{W}^{-}$, $e^{+}\gamma \to e^{+}{\gamma }^{\ast }\gamma \to e^{+}{W}^{-}{W}^{+}$ and $e^{+}{e}^{-}\to e^{+}{\gamma }^{\ast }{\gamma }^{\ast }{e}^{-}\to e^{+}{W}^{-}{W}^{+}{e}^{-}$ at the CLIC are a very good prospect for probing the anomalous $W^{+}{W}^{-}\gamma$ couplings.
