摘要
We explore some more consequences of the SU(3)(L)xU(1)(N) electroweak model with right-handed neutrinos. By introducing the Z-Z' mixing angle phi, the exact physical eigenstates for neutral gauge bosons are obtained. Because of the mixing, there is a modification to the Z(1) coupling proportional to sin phi. The data from the Z decay allow us to fix the limit for phi as -0.0021 less than or equal to phi less than or equal to 0.000 132. From the neutrino neutral current scatterings, we estimate a bound for the new neutral gauge boson Z(2) mass in the range of 300 GeV, and from symmetry-breaking hierarchy a bound for the new charged and neutral (non-Hermitian) gauge bosons Y-+/-,X(0) are obtained.
