Abstract
Recent lattice analyses of the Dπ scattering by Hadron Spectrum Collaboration (HadSpec) report only one pole in the D∗0 channel. This is in odds with the unitarised chiral perturbation theory analyses, which predict the D∗0 (2300) as the interplay of two poles. We provide an explanation for this contradiction—the existence of a hidden pole. We further show that the hidden pole can be better extracted from the lattice data by imposing SU(3) flavour constraints on the fitting amplitudes.
