Abstract

Baryon-baryon interactions other than nucleon-nucleon interaction (nuclear force) including nucleon-hyperon and hyperon-hyperon are very important for understanding of structure of hyper nuclei, exotic hadrons, and inner structure of neutron stars. In my talk, I report the recent progress on the baryon-baryon interactions directly calculated by the lattice QCD using the supercomputer Fugaku in Japan. In addition to recent improvement of computing power of (super)computers, two theoretical techniques, time-dependent HAL QCD method and Misner's method are essential to obtain precise results of the baryon-baryon interaction. I will explain the two methods and report the recent results of the interactions of baryons.
