Investigation of anomalous triple gauge couplings in $\mu\gamma$ collision at multi-TeV muon colliders

The pursuit of discovery in particle physics has always required study at the highest possible energies. Multi-TeV muon colliders, which have important advantages, offer unprecedented potential for investigating new physics beyond the Standard Model. We extensively assume a range of center-of-mass energies from 3 to 100 TeV and a range of integrated luminosities from 1 to 1000 ab$^{-1}$ for future multi-TeV muon colliders. We perform a phenomenological study of the anomalous $WW\gamma$ couplings via the process $\mu^+ \mu^-\,\rightarrow\,\mu^+\gamma^* \mu^-\,\rightarrow\,\mu^+W^-\nu_\mu$ using a model-independent analysis in the effective field theory framework at multi-TeV muon colliders. The sensitivity estimates obtained for the anomalous $WW\gamma$ couplings at systematic uncertainties of $\delta_{sys}=0$, $3$, $5\%$ are compared with the experimental results. Our best sensitivity limits at 95$\%$ confidence level for $c_{WWW}/{\Lambda^2}$, $c_{\widetilde{W}WW}/\Lambda^2$, $c_{B}/{\Lambda^2}$, $c_{W}/{\Lambda^2}$ and $c_{\widetilde{W}}/\Lambda^2$ couplings are $[-0.00480; 0.00559]\,\text{TeV}^{-2}$, $[-0.00256; 0.00262]\,\text{TeV}^{-2}$, $[-0.03965; 0.03975]\,\text{TeV}^{-2}$, $[-0.03874; 0.03886]\,\text{TeV}^{-2}$ and $[-0.54591; 0.54689]\,\text{TeV}^{-2}$ at the multi-TeV muon collider with center-of-mass energy of 100 TeV and integrated luminosity of 1000 ab$^{-1}$, respectively.Comment: 23 pages, 4 figures, 9 table
