摘要
We analyse all the neutral-current phenomena following from the general class of gauge models based on the group SU(2) L ⊗ SU(2) R ⊗ U(1). It is found that the neutral-current couplings in these models bear a remarkable similarity to those in the standard Weinberg-Salam gauge model. The parameter which plays the role of sin2θ{symbol}w is found to lie between 0 and 1/2. Comparison with experimental data shows that even a model with the ratio of the masses of the two Z bosons as small as 1.9 is not ruled out. © 1979 Indian Academy of Sciences.
