Search for photoproduction of axion-like particles at GlueX

Axion-like particles (ALPs) are hypothetical pseudoscalars found in many extensions to the Standard Model. Recently, MeV-to-GeV scale, henceforth QCD-scale, ALPs have received considerable interest. We perform a dedicated search for photoproduction of QCD scale ALPs using the full GlueX Phase I dataset in the gammagamma and pi^+\pi^-\pi^0 channels. The analysis is currently blinded and under collaboration review. In this talk, we will present the general search strategy and the expected sensitivity.
