Abstract：
We studied an SU(3) _L×U(1) _Xelectroweak model. By requiring M2z1-M2w/ cos ²θw to be less than experimental value we abtain a lower bound on M _Z′The relation between M _Z′and M _U(M _V) then gives a lower bound on M _U(M _V). We further consider the K _L－K _Smass difference due to Z′ exchange and obtain stronger lower bounds on M _Z′and M _U(M _V).
