Mass of the higgs versus fourth generation masses
PACS: 12.15.Lk, 12.60.-i, 14.80.Bn
Abstract
The predicted value of the higgs mass mH 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: mH, mU, mD, mN, mE. The LEPTOP fit of the precision electroweak data is compatible (in particular) with m_H \sim 300 GeV, m_N \sim 50 GeV, m_E
\sim 100 GeV, m_U +m_D \sim 500 GeV, and |m_U -m_D| \sim 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.
