Second , the quark potential has to be at present determined phe - nomenologically due to qcd nonperturbation and the mechanism of quark confinement is still in search 尹其次,由于夸克勢(shì)只能唯象地得到,夸克禁閉機(jī)制及其對(duì)重介子的影響仍在探索之中
We obtain a new quark potential from the effective dilaton - gluon - coupling inspired by superstring theory , and by using this static potential , we explore the mechanism of quark confinement through calculations of the spin - average energy levels , the widths of the leptonic decays and radiative transitions for heavy quarkonium . the obtained results are compared with that of the cornell potenial 由規(guī)范場(chǎng)理論的超弦理論所激發(fā)的伸縮子一膠子有效藕合,給出了一個(gè)新的靜態(tài)夸克一反夸克勢(shì),討論了此勢(shì)模型下重介子的自旋平均能譜、輕子衰變和輻射躍遷寬度,并與cdrn叭勢(shì)模型所得到的相應(yīng)結(jié)果作了比較
