Description
The latest electroweak precision data are analyzed assuming the existence of the fourth generation of leptons (N,E) and quarks (U,D), which are weakly mixed with the known three generations. If all four new particles are heavier than Z boson, quality of the fit for the one new generation is as good as for the Standard Model (SM). In the case of neutral leptons with masses around 50 GeV ('partially heavy extra generations') the minimum of χ2 is between one and two extra generations. SM prediction of light higgs is no more valid if new generations exist (Author)
