14 Mar 2002 | | Journal: | JETP Lett. 76 (2002) 127-130; Pisma Zh.Eksp.Teor.Fiz. 76 (2002) 158-161 | | Subject: | hep-ph | | 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 $m_H sim 300$ 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. | | Source: | arXiv, hep-ph/0203132 | | Services: | Forum | Review | PDF | Favorites | |
