Baryon Resonances in the Large Nc Collective Theory

  • 摘要: 最近Diakonov考虑了大Nc平均场近似下重子共振态谱的海夸克效应并提出重子共振态谱的集体激发理论,该理论恰好是SU(6) 夸克模型的一种推广。检查了Diakonov重子谱理论中介子张量势的物理含义并给出重子共振态谱公式参数的数值优化。发现,重子共振态谱公式能够与2 GeV以下重子谱良好吻合。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.
