  "abstract": "We study the sensitivity of the Future Circular Collider in electron-positron mode (FCC-ee) to the axion-like particle (ALP) couplings with leptons via the process $e^{+}e^{-} \\rightarrow γγjj$ at the center-of-mass energy $\\sqrt{s}=91$ GeV with the integrated luminosity $\\mathcal{L}=150~\\text{ab}^{-1}$. We analyze three scenarios, $\\mathbf{c}_R=0$, $\\mathbf{c}_L=0$ and $\\mathbf{c}_R=\\mathbf{c}_L$, for both unpolarized and polarized beams with $(P_{e^-}, P_{e^+}) = (+80\\%, -80\\%)$, and derive projected lower limits on the effective coupling strengths. The polarized case provides higher sensitivity than the unpolarized case. Specifically, for the $\\mathbf{c}_R=0$ scenario (probing the ALP-neutrino coupling $\\text{Tr}(g_{aνν})/f_a$), the projected sensitivity in the polarized case reaches approximately $0.0105~\\text{GeV}^{-1}$ for the ALP mass in the range $10$--$24$ GeV; for $\\mathbf{c}_L=0$ (probing the ALP-charged lepton coupling $\\text{Tr}(g_{a\\ell\\ell})/f_a$), it reaches $0.0174~\\text{GeV}^{-1}$ in the $10$--$27$ GeV range; and for $\\mathbf{c}_R=\\mathbf{c}_L$ (probing the ALP-neutrino coupling $\\text{Tr}(g_{aνν})/f_a$), it reaches $0.00394~\\text{GeV}^{-1}$ in the $45$--$80$ GeV range. In these ALP mass ranges, our projected sensitivities are complementary to the projected sensitivities from other search channels at future colliders.",
