摘要：

Using our previous bounds on DELTArho and the Z-Z' mixing angle xi(N) in the SU(2)L x SU(2)R x U(1)(B-L) model from the Z line shape and energy-dependent forward-backward asymmetries of the 1990 data from CERN LEP, we obtain a strong lower bound congruent-to 439 GeV at 90% C.L. on the right-handed charged gauge boson mass for m(t) = 200 GeV using commonly chosen Higgs triplets, which becomes stronger for doublet Higgs fields. It is independent of the neutrino mass or of assumptions about the right-handed quark mixing matrix. Consequences of more exotic Higgs multiplets are also discussed.
