$D_1$ and $D_2$ resonances in coupled-channel scattering amplitudes from lattice QCD

Nicolas Lang, David J. Wilson

Isospin-1/2 charmed axial-vector $D^{\ast }\ddot{I}€-D^{\ast }\hat{I}\cdot -D_s^{\ast }\bar{K}$ scattering amplitudes are computed, along with interactions in several other $I=1/2$ $J^P$ channels. Using lattice QCD,…
