  In the unified subquark model of all fundamental particles and forces, the
mass of the Higgs boson in the standard model of electroweak interactions
($m_H$) is predicted to be about $2\sqrt{6}m_W/3$ (where $m_W$ is the mass of
the charged weak boson, $W$), which agrees well with the experimental values of
about 125 GeV recently found by the ATLAS and CMS Collaborations at the LHC. It
seems to indicate that the Higgs boson is a composite of the iso-doublet spinor
subquark-antisubquark pairs well described by the unified subquark model with
either one of subquark masses vanishing or being very small compared to the
other. In the unified composite model, the masses of excited weak gauge bosons,
$W^\ast$ and $Z^\ast$, and Higgs bosons, $H^\ast$, as well as excited quarks
and leptons are all predicted to be of the order of the composite mass scales,
say 1 TeV, and to satisfy the relation of $m_Wm_{W^\ast} =
m_Zm_{Z^\ast}\cos\theta_w$ (where $\theta_w$ is the weak mixing angle). It
strongly suggests that the excess of di-boson resonance events recently found
by the ATLAS Collaboration at about 2 TeV may be explained by the productions
and decays of the first excited states of either one of the weak and Higgs
bosons, and the glueballs.
