Coupled-channel scattering of $DD,D{D}^{\ast }$ and $D^{\ast }{D}^{\ast }$ in isospin-$1$ from lattice QCD

Nelson Pitanga Lachini, Christopher E. Thomas, David J. Wilson

The first coupled-channel determination of two-body $D$ and $D^{\ast }$ scattering amplitudes in isospin-$1$ from lattice quantum chromodynamics is presented. Using three lattice volumes…
