Non-perturbative field-theory arguments and lattice simulations
suggest
the existence of a second resonance of the Higgs field in the
Standard
Model, with a mass close to 700 GeV. Remarkably, several small
enhancements in precisely the same energy ballpark and from
different
processes can be seen in both ATLAS and CMS data, with a combined
statistical significance that should not be ignored. Non-
perturbative
coupled-channel unitarity is proposed to estimate the width of the
suggested resonance, resulting from its dominant top-antitop decay
and
mixing with the light Higgs at 125 GeV.
