Abstract

We propose a new method to extract hadron interactions above inelastic threshold from the Nambu–Bethe–Salpeter amplitude in lattice QCD. We consider the scattering such as <i>A</i> + <i>B</i> → <i>C</i> + <i>D</i>, where <i>A</i>, <i>B</i>, <i>C</i>, <i>D</i> are names of different 1-particle states. An extension to cases where particle productions occur during scatterings is also discussed.<BR><BR>(Communicated by Toshimitsu YAMAZAKI, M.J.A.)
