| contents | We investigate the sensitivities on the Wilson coefficients of dimension-six operators associated with the anomalous $Hγγ$, $HγZ$ and $HZZ$ vertices through the process $μ^- μ^+ \rightarrow Zγγ$ at future muon collider. Signal events involving Higgs-gauge boson interactions and relevant backgrounds events at the muon collider designed with a center-of-mass energy of 10 TeV and an integrated luminosity of 10 ab$^{-1}$ are generated in Madgraph within the framework of the model-independent Standard Model effective field theory. Realistic detector effects of the muon collider detector are simulated by Delphes. The limits at 95% C.L., $3σ$ and $5σ$ on the coefficients $\overline{c}_{HB}$ and $\overline{c}_{HW}$ are obtained without and with systematic uncertainty of 15% and compared with the present experimental and phenomenological limits. |
