Renormalization group analyses of particle masses in full four-generation fermion condensate scheme

The renormalization group analyses of the masses of the heavy fermions and the Higgs boson, including the discussions of possible fixed points and applicability of perturbation theory, are expounded in the full four-generation quark-lepton condensate scheme of the minimal electroweak symmetry breaking. The results also indicate that the model could accommodate itself to the top-quark mass mt = 160 - 180GeV. The predicted Higgs boson mass is in fact not too sensitive to the above change of mt. It is also found that for a model without the fourth generation of leptons, the limitation to Λ imposed by the requirement that the masses of the fourth generation of extra quarks are bigger than mt = 174GeV could be greatly relaxed up to ≤ 1011 GeV.
