Description
One or two $D_0^*$ resonances with strangeness $S=0$, isospin $I=1/2$ dynamically generated in pseudo-scalar meson octet and heavy mesons scattering are still a puzzle. In this talk, I will present that there are two $D_0^*$ resonances generated by ChPT up to NLO. The LECs of the interaction are constrained by the energy levels simulated by LQCD in $(S,I)=(0,1/2)$, $(1,0)$, $(-1,0)$, and $(-1,1)$ sectors. By studying the pion mass dependence of the two resonances and extrapolating to SU3 flavor symmetry point, we show that one resonance is connected to irreducible presentation $\mathbf{\bar{3}}$, and the other resonance is connected to $\mathbf{6}$.
