✦ Synopsis

Using the SU 6 quark-model baryon-baryon interaction recently developed by the Kyoto-Niigata group, we calculate NN, N and N G-matrices in ordinary nuclear matter. This is the first attempt to discuss the and single-particle potentials in nuclear medium, based on the realistic quarkmodel potential. The potential has the depth of more than 40 MeV, which is more attractive than the value expected from the experimental data of -hypernuclei. The potential turns out to be repulsive, the origin of which is traced back to the strong Pauli repulsion in the N(I = 3/2) 3 S 1 state.
