Findings
Successfully extracted nucleon-nucleon potentials from lattice QCD
Reproduced qualitative features of modern NN potentials
Extended method to hyperon-nucleon interactions
Abstract
We report on new attempt to investigate baryon-baryon interactions in lattice QCD. From the Bethe-Salpeter (BS) wave function, we have successfully extracted the nucleon-nucleon () potentials in quenched QCD simulations, which reproduce qualitative features of modern potentials. The method has been extended to obtain the tensor potential as well as the central potential and also applied to the hyperon-nucleon () interactions, in both quenched and full QCD.
