摘要 使用超弦理论激发的伸缩子 胶子有效耦合得到的重夸克势研究了重介子的能谱,采用统一的方式来求解Salpeter方程和Schr dinger方程,以便能真实地比较相对论动能修正的效应.发现相对论Salpeter方程更好地说明了实验上观察到的重介子能级. Heavy quarkonium spectra are investigated within the heavy quark potential model, which is obtained from the dilatongluon (motivated by superstring theory) effect coupling. In order to reflect the effects of relativistic kinetic correction we solve the Salpeter equation and Schrdinger equation in the same way. It is shown that the Salpeter equation with the corrections of relativistic kinetic energy gives the better results than the Schrdinger equation for heavy quarkonium spectra.
