摘要：
The recent data on Z boson decays and on the W mass are analyzed from the point of view of the possible existence of extra generations of leptons and quarks with masses greater than or equal to m(Z)/2. Present experimental accuracy is not sufficient to exclude the existence of one extra generation of leptons and quarks, even with masses as low as 50 GeV.
