      abstract     = {It was demonstrated in a series of papers employing
                      unitarized chiral perturbation theory that the phenomenology
                      of the scalar open-charm state, the , can be understood as
                      the interplay of two poles, corresponding to two
                      scalar-isospin doublet states with different SU(3) flavor
                      content. Within this formalism the lightest open charm
                      positive parity states emerge as being dynamically generated
                      from the scattering of the Goldstone-boson octet off D
                      mesons, a picture that at the same time solves various
                      problems that the experimental observations posed. However,
                      in recent lattice studies of scattering at different pion
                      masses only one pole was reported in the channel, while it
                      was not possible to extract reliable parameters of a second
                      pole from the lattice data. In this paper we demonstrate how
                      this seeming contradiction can be understood and that
                      imposing SU(3) constraints on the fitting amplitudes allows
                      one to extract information on the second pole from the
                      lattice data with minimal bias. The results may also be
                      regarded as a showcase how approximate symmetries can be
                      imposed in the K-matrix formalism to reduce the number of
                      parameters.},
