Through the scattering of light-pseudoscalar mesons $(\ensuremath{\pi},K,\ensuremath{\eta},{\ensuremath{\eta}}^{\ensuremath{'}})$ off charmed mesons $(D,{D}_{s})$, we study the ${D}_{s0}^{*}(2317)$ state and other relevant charm scalar mesons in a unitarized chiral effective field theory approach. We investigate the charm scalar meson poles with different strangeness ($S$) and isospin ($I$) quantum numbers as well as their …
