【Abstract】 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.更多还原
