| contents | We investigate the possibility of detecting the leptophilic gauge boson $Z_x$ predicted by the $U(1)_{L_e-L_μ}$ model via the processes $e^+e^-\rightarrow\ell^+\ell^-Z_x(Z_x\rightarrow \ell^+\ell^-)$ and $e^+e^-\rightarrow \ell^+\ell^-Z_x(Z_x\rightarrow ν_\ell\bar{ν_\ell})$ at the Circular Electron Positron Collider (CEPC) with the center of mass energy $\sqrt s=240$ GeV and the luminosity $\mathcal{L}=5.6$ $\mathrm{ab^{-1}}$. We give the expected sensitivities of the CEPC to the parameter space at $1σ$, $2σ$, $3σ$ and $5σ$ levels. |
