Abstract
The deviation δQW of the weak charge from its standard model prediction due to the mixing of the W boson with the charged bilepton Y as well as of the Z boson with the neutral Zâ² and the real part of the non-Hermitian neutral bilepton X in the economical 3-3-1 model is established. Additional contributions to the usual δQW expression in the extra U(1) models and the left-right models are obtained. Our calculations are quite different from previous analyzes in this kind of the 3-3-1 models and give the limit on mass of the Zâ² boson, the Z-Zâ² and W-Y mixing angles with the more appropriate values: MZâ²>564GeV, â0.018
