Abstract
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, m U, m D, m N, m E. The LEPTOP fit of the precision electroweak data is compatible (in particular) with m H∼ 300 GeV, m N∼50 GeV, m E∼100 GeV, m U+m D∼500 GeV, and |m U−m D|∼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.Keywords
