Abstract
The authors explore the content of the ${D}_{s0}^{*}(2317)$ meson in a lattice QCD study. Using several local two-quark, local tetraquark, and two-meson, i.e. molecular, interpolating fields, they find that the tetraquark contribution to the ${D}_{s0}^{*}(2317)$ meson is negligible, at least for the pion mass, of about 296 MeV, used in this study.
