interactions are weak near threshold in QCD
David J. Wilson, Jozef J. Dudek, Robert G. Edwards +1
We study near-threshold scattering in and -wave to determine whether or not resonances or bound states are present. Working in the approximation where charm-annih…
Coupled-channel scattering of and in isospin- from lattice QCD
Nelson Pitanga Lachini, Christopher E. Thomas, David J. Wilson
The first coupled-channel determination of two-body and scattering amplitudes in isospin- from lattice quantum chromodynamics is presented. Using three lattice volumes…
Isotensor scattering with a resonant subsystem from QCD
Raúl A. Briceño, Maxwell T. Hansen, Andrew W. Jackura +2
This work presents a lattice quantum chromodynamics (QCD) determination of scattering amplitudes for the isospin-2 channel with angular momentum and parity .…
Near-threshold states in coupled scattering from lattice QCD
Travis Whyte, David J. Wilson, Christopher E. Thomas
The first determination of doubly-charmed isospin-0 coupled-channel scattering amplitudes from lattice QCD is presented. The finite-volume spectrum is compu…
scattering and an exotic virtual bound state at the flavour symmetric point from lattice QCD
J. Daniel E. Yeo, Christopher E. Thomas, David J. Wilson
Elastic wave scattering of a charm meson with a light pseudoscalar meson in is investigated in the flavour , and $\overline{\mathbf{15…
