We study collider implications of variant axion models which naturally avoid the cosmological domain wall problem. We find that in such models the branching ratio of h → can be enhanced by a factor of 5 up to 30 as compared with the standard model prediction. The h → process is therefore a promising channel to discover a light Higgs boson at the LHC and to probe the Peccei-Quinn charge assignment of the standard model fields from Yukawa interactions.
