Abstract

We comment on the Standard Model Higgs boson evidence from LHC. We propose that the new resonance at 125 GeV could be interpreted as a pseudoscalar meson with quantum number J^PC = 0^{- +}. We show that this pseudoscalar could mimic the decays of the Standard Model Higgs boson in all channels with the exception of the decay into two leptons that is strongly suppressed due to charge-conjugation invariance.
