In this Letter we show that pseudoscalar meson leptonic decay data can be used to set stringent limits on the mass $$m$$W$$_{R}$$ 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 $$m_N$$ in the range 50 < $$m_N$$/MeV < 1900 one can constraint $$m$$W$$_{R}$$ ≳ (4–19) TeV at 90% CL. This provides the most stringent experimental limits on the $$W_R$$ mass to date for this heavy neutrino mass range.
