Hadron Spectroscopy and Interactions

Coupled-channel scattering from lattice QCD


  • David WILSON

Primary authors


I will discuss recent coupled-channel scattering calculations from the Hadron Spectrum Collaboration. Utilising the variational method with large bases of operators, including those that resemble q-qbar and meson-meson like constructions, many energy levels can be extracted. These spectra are then used with the coupled-channel extensions of Lüscher's finite volume formalism, to determine the infinite volume coupled-channel scattering amplitudes. I will report on recent calculations that have been able to determine resonance poles and channel couplings in several quantum numbers.
