Abstract
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.

In particular, we explore the possibility that the new boson with a mass of approximately 125 GeV [ref] observed at the LHC is consistent with a neutral pseudoscalar top-pion state.[The possibility that the boson observed at the LHC is a pseudo-scalar has been considered by a number of authors recently [ref] .] We demonstrate that a neutral pseudoscalar top-pion can generate the diphoton signal at the observed rate.
