THE HEAVY QUARKONIUM SPECTRUM OF ANHARMONIC OSCILLATORS CONFINEMENT POTENTIAL

  • The heavy quarkonium spectra were discussed with a confinement potential of the form Vc(r)=1/2kr2+λr4 by using the Hypervirial Pade Approach. With choice of suitable parameters, we calculated the binding energy levels of cc and bb systems which provide good agreement with the experimental values.

THE HEAVY QUARKONIUM SPECTRUM OF ANHARMONIC OSCILLATORS CONFINEMENT POTENTIAL

    Corresponding author: ZHOU Yuan-Hai,

Abstract: The heavy quarkonium spectra were discussed with a confinement potential of the form Vc(r)=1/2kr2+λr4 by using the Hypervirial Pade Approach. With choice of suitable parameters, we calculated the binding energy levels of cc and bb systems which provide good agreement with the experimental values.
