Extraction of Hadron Interactions above Inelastic Threshold in Lattice QCD
Abstract
We propose a new method to extract hadron interactions above inelastic threshold from the Nambu-Bethe-Salpter amplitude in lattice QCD. We consider the scattering such as A+B→ C+D, where A,B,C,D are names of different 1-particle states. An extension to cases where particle productions occur during scatterings is also discussed.
