Abstract
Using our previous bounds on Δρ and the Z-Z' mixing angle ξN in the SU(2)L⊗SU(2)R⊗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 ~439 GeV at 90% C.L. on the right-handed charged gauge boson mass for mt=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.
