Description
The Hadron Spectrum Collaboration (HSC) presented new results on
two of their ensembles for s-wave scattering phase shifts
in the open-charm sector of QCD. For such ensembles we have made
predictions that are based on the chiral Lagrangian that were published two years ago. In this talk
we confront our phase shifts with those of HSC. A remarkably
consistent picture emerges. In particular there is mounting
evidence for the existence of a flavour sextet state in the $\pi D$
and $\pi D^*$ channels, that show a striking quark-mass dependence.
