New limits on \(W_R\) from meson decays
Date:
In this talk 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 \(50<m_N/{\rm MeV} <1900\) one can constraint \(m_{W_R} \gtrsim (4-19)\) TeV at 90% CL. This provides the most stringent experimental limits on the \(W_R\) mass to date for this heavy neutrino mass range.
