Nonperturbative Effect of Nonstrange Baryonic Spectrum

  • We study N and △ spectra by solving Schrodinger equation for the three quark system in the mixture of configurations. Besides the perturbative effect of usual one-gluon exchange, the nonperturbative effects of both color screening predicted by the LGT calculation and pion(sigma) exchange due to the chiral symmery breaking are also included in present quark-quark potential. The agreement of the baryonic spectra obtained with the experiment is improved.

Abstract: We study N and △ spectra by solving Schrodinger equation for the three quark system in the mixture of configurations. Besides the perturbative effect of usual one-gluon exchange, the nonperturbative effects of both color screening predicted by the LGT calculation and pion(sigma) exchange due to the chiral symmery breaking are also included in present quark-quark potential. The agreement of the baryonic spectra obtained with the experiment is improved.
