We study the two body decay of mesons using the helicity formalism. We find that to explain the ratio of partials wave amplitudes (PWAs) of the decay, the Lagrangian must include derivative interactions in addition to contact interactions. We estimate the coupling constants for the $1^{++}\to1^{--}0^-$, $1^{+-}\to1^{--}0^-$, $2^{-+}\to2^{++}0^-$, and $2^{-+}\to1^{--}0^-$ decays by fitting the ratio of the PWAs and the decay widths to the available data and predict the ratios to some new decays.
