Abstract

We study the color-current Nambu and Jona-Lasinio model for mesons and diquarks and find that the masses of diquarks are the same as meson masses of the same spin and the opposite parity with the same flavor content due to the Pauli-Gürsey symmetry. By taking the weak coupling diquark-quark model for baryons, we calculate the baryon masses with the use of the known meson masses through the Pauli-Gürsey symmetry. The agreement with the existing data is extremely good. We predict several SU(4) baryon masses with charms to be checked experimentally.
