摘　　要：使用从超弦理论激发的伸缩子与胶子耦合的有效理论得出的重夸克反夸克势 ,研究了重夸克反夸克系统的自旋平均能级 .所得结果与实验上肯定的实验数据符合较好 .同时 ,我们估计的伸缩子质量是大约 6 0MeV ,它位于伸缩子质量的许多理论方案预期的范围之内 .Using the heavy quark antiquark potential which emerges from an effective dilaton gluon coupling inspired by the superstring theory, we study the energy levels of heavy quark antiquark systems. The obtained results are in agreement with the available experimental data. As by production, the dilaton mass is estimated to be around 60 MeV which lies within the range predicted by many theoretical scenario of the dilaton mass.
