伸缩的

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.
