Quarkonium resonance identified with the 125 GeV boson    [PDF]

A chiral and $U_A(1)$ symmetry breaking derivation of a 125 GeV $\zeta^0$ meson resonance, identified with the newly discovered boson at the LHC, is presented in which the meson resonance is composed of a QCD mixture of bound bottom and top quarks and anti-quarks. The decay rates of the 125 GeV $\zeta$ meson resonance are calculated and compared to the standard model Higgs boson decay rates. The decay rate for $\zeta\rightarrow gg$ is larger than the Higgs boson decay rate, but the $\zeta$ meson production cross section is reduced by a QCD correction factor $\Delta\sigma$. The decay rate for $\zeta\rightarrow Z\gamma$ is larger than the Higgs decay rate, while the decay rate for $\zeta\rightarrow ZZ^*$ is approximately twice the size of the predicted Higgs boson decay rate. The $\zeta\rightarrow WW^*$ decay rate is smaller than the Higgs boson decay rate. The rates for $\zeta\rightarrow\tau^+\tau^-$, $\zeta\rightarrow b\bar b$ and $\zeta\rightarrow c\bar c$ are suppressed compared to the Higgs boson decay rates. The signal strength for $\zeta\rightarrow\gamma\gamma$ can be fitted to be twice the Higgs boson signal strength, which is consistent with the current result measured at CMS and ATLAS. New branching ratios obtained at the LHC can distinguish between the standard model Higgs boson and the heavy composite $\zeta$ meson resonance.
