Quarkonium resonance identified with the 125 GeV boson

Abstract

The 125 GeV resonance discovered at the LHC could be a heavy quarkonium, spin 0 pseudoscalar meson ${\zeta }^0$. The decay rates of the ${\zeta }^0$ meson resonance are calculated and compared to the standard model Higgs boson decay rates. The branching ratios and signal strengths for $\zeta \to \gamma \gamma$, $\zeta \to Z\gamma$, $\zeta \to Z{Z}^{\ast }$ and $\zeta \to W{W}^{\ast }$ are approximately the same as the Higgs boson branching ratios and signal strengths. The decay rates for $\zeta \to {\tau }^{+}{\tau }^{-}$, $\zeta \to b\bar{b}$ and $\zeta \to c\bar{c}$ are suppressed compared to the Higgs boson decay rates. Accurate branching ratios and signal strengths obtained at the LHC can distinguish between the standard model Higgs boson and the heavy composite $\zeta$ meson resonance.
