Using a K*(892)+D*(2010) pole model fitted to BESIII data, the authors show the D* pole can mimic the S-wave contribution previously attributed to the kappa scalar meson in D_{e4} decays.
The central value of |Vcs|(De4) turns out to be smaller than but consistent with other (most precise) determinations

Semileptonic $D_{e4}$ decays: hadronic dynamics and the determination of $|V_{cs}|$
Using a K*(892)+D*(2010) pole model fitted to BESIII data, the authors show the D* pole can mimic the S-wave contribution previously attributed to the kappa scalar meson in D_{e4} decays.
