Abstract

Precisionmeasurements 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.
