Abstract
Recently, Diakonov considered the sea quark effect of baryon resonance spectrum in the large Nc mean field approximation and put forward the collective excitation theory of baryon resonance spectrum, which is an extension of the SU(6) quark model. In this paper we examine the implications of the meson tensor potential of the Diakonov’s baryon spectrum theory and provide a numerical optimization of the parameters in the baryon resonance spectrum formula. The resulted baryon resonance spectrum formula is in good agreement with the spectra data below 2 GeV.
