Isospin-1/2 $D\pi$ scattering and the lightest $D_0^{\ast }$ resonance from lattice QCD

Luke Gayer, Nicolas Lang, Sinéad M. Ryan +3

Isospin-1/2 $D\pi$ scattering amplitudes are computed using lattice QCD, working in a single volume of approximately $(3.6\mathrm{fm}{)}^3$ and with a light quark mass corresponding…
