Abstract

If isotriplet hybrid mesons (

π_{H}' s

) with

J^{PC} = 0^{- +}

exist and their masses are close to that of the

D_{s}^{+}

, they may play a particular role in suppressing efficiently the amplitude for the

D_{s}^{+} \to π^{+} ρ^{0}

decay in consistency with experiment, while corresponding contributions of other members of the same multiplet are also compatible with other charm-meson decays.
