Pion mass dependence in $D\pi$ scattering and the $D_0^{\ast }(2300)$ resonance from lattice QCD

Haobo Yan, Chuan Liu, Liuming Liu +2

Lattice QCD results for isospin $I=\frac{1}{2}$ $D\pi$ scattering are presented. Utilizing a series of $N_{\text{f}}=2+1$ Wilson-Clover ensembles with pion masses of $m_π\approx 132,…
