Description
A few years ago, we proposed a method to extract potentials from the Nambu-Bethe-Salpeter wave function and indeed obtained the nucleon-nucleon potential in lattice QCD. In this talk, as an extension of this method, we propose a new method to extract information of hadron interactions in lattice QCD above the inelastic threshold. After theoretical considerations of this method, we present results from a toy model to show a main idea of this method as well as from lattice QCD to extract hyperon-hyperon potentials.
We briefly discuss other applications.
