Has A 125 GeV Pseudoscalar Resonance Been Observed at the LHC?    [PDF]

J. W. Moffat

We conjecture that a 125 GeV resonance $\zeta^0$ with $J^{PC}=0^{-+}$ composed of a $(t\bar t+b\bar b)/\sqrt{2}$ quark state with flavor mixed t-quark and b-quark masses has been observed at the LHC. The dominant decay mode of this pseudoscalar particle is $\zeta^0\rightarrow 2\gamma$, while the $WW^*, ZZ^*, Z\gamma, b\bar b, \tau^+\tau^-$ will not be detected at the LHC. The decay $\zeta^0\rightarrow\gamma +\ell^+ +\ell^-$ could also be detected where $\ell^+$ and $\ell^-$ denote leptons. Another pseudoscalar $J^{PC}=0^{-+}$ resonance $\zeta^{0'}$ is predicted to exist at the mass $m_{\zeta^{0'}}\sim 322$ GeV.
