Abstract

We consider the scenario in which the new strong dynamics is responsible for the formation of the 125 GeV Higgs boson. The Higgs boson appears as composed of all known quarks and leptons of the Standard Model. The description of the mentioned strong dynamics is given using the $ζ$ regularization. It allows us to construct the effective theory without ultraviolet divergences in which the $1 / N_{c}$ expansion works naturally. It is shown that in the leading order of the $1 / N_{c}$ expansion, the mass of the composite $h$ boson is given by $M_{h} = m_{t} / \sqrt{2} \approx 125 GeV$ , where $m_{t}$ is the top-quark mass.
