Once more on extra quark-lepton generations and precision measurements

Abstract : Precision measurements of Z-boson parameters and W-boson and t-quark masses put strong constraints on non SU(2)×U(1) singlet New Physics. We demonstrate that one extra generation passes electroweak constraints even when all new particle masses are well above their direct mass bounds.
