A bstract We study the photophobic ALP model in high-mass regions under LHC Run-II. Since the ALP is predominantly coupled with electroweak gauge bosons such as ZZ , WW , and Zγ , and less with di-photon, the model may be probed via multi-boson final-state processes. We find that on-shell ALP productions with Zγ final states currently provide the best sensitivities for m a > 40 GeV.
