Abstract
In this Letter we show that pseudoscalar meson leptonic decay data can be used to set stringent limits on the mass mWR of a right-handed vector boson, such as the one that appears in left-right symmetric models. We have shown that for a heavy neutrino with a mass Mn in the range 50<mN/MeV<1900 one can constraint mWR ░(4–19) TeV at 90% CL. This provides the most stringent experimental limits on the WR mass to date for this heavy neutrino mass range.
