NEW BOUND ON RIGHT-HANDED CHARGED GAUGE BOSON MASS

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 ene rgy-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. o n the right-handed charged gauge boson mass for m(t) = 200 GeV using c ommonly chosen Higgs triplets, which becomes stronger for doublet Higg s fields. It is independent of the neutrino mass or of assumptions abo ut the right-handed quark mixing matrix. Consequences of more exotic H iggs multiplets are also discussed.
