We conjecture that a 125 GeV resonance ζ0 with JPC=0-+ composed of a quark-antiquark state may have been observed at the LHC. The decay modes of this pseudoscalar particle are determined using the non-relativistic quark model. The leading order partial decay widths for the decays of the pseudoscalar quarkonium resonance ζ0→ γγ and ζ0→ gg are compared to the standard model Higgs particle decays H0→ γγ and H0→ gg. An experimental analysis at the LHC of the observed production cross sections for the ζ0 and the Higgs particle could distinguish between a heavy quarkonium ζ0 particle and a light Higgs particle at 125 GeV.
