| contents | The expected precision on measuring the $σ(e^+ e^- \rightarrow ZH) \times Br(H\rightarrow W^+W^-)$ in the fully leptonic decay mode at the Future Circular Collider (FCC) is presented. We consider two FCC-ee scenarios: $\sqrt{s} =240$ GeV centre-of-mass energy with a luminosity of 10.8$\rm{~ab}^{-1}$ and $\sqrt{s} =365$ GeV centre-of-mass energy with a luminosity of 3.12$\rm{~ab}^{-1}$. Our results indicate that a relative uncertainty of 2.9\% and 6.8\% can be achieved on measurements of $σ(e^+ e^- \rightarrow ZH) \times Br(H\rightarrow W^+W^-)$ in the fully leptonic decay mode at $\sqrt{s} =240$ GeV and $\sqrt{s} =365$ GeV, respectively. |
