摘要：

The predicted value of the higgs mass m(H) is analyzed assuming the existence of the fourth generation of leptons (N, E) and quarks (U, D). The steep and flat directions are found in the five-dimensional parameter space: m(H) similar to m(U), m(D), m(N), m(E). The LEPTOP fit of the precision electroweak data is compatible (in particular) with m(H) similar to 300 GeV, m(N) similar to 50 GeV, m(E) similar to 100 GeV, m(U) + m(D) similar to 500 GeV, and \m(U) - m(D)\ similar to 75 GeV. The quality of fits drastically improves when the data on b- and c-quark asymmetries and new NuTeV data on deep inelastic scattering are ignored. (C) 2002 MAIK "Nauka/Interperiodica".
