An approach to the calculation of nonperturbative energy level shifts in heavy quarkonia
Description
In order to test a method of calculating heavy quarkonium level shifts due to vacuum fields an exactly solvable generalized oscillator model proposed by Zalewski has been studied. Results of the calculation of the ground-state energy in the Zalewski model are presented and compared for different approximations with the exact ground state energies. It is concluded that the calculation of properties of heavy quarkonia can be reliable only when supplied with improved knowledge of the QCD vacuum and excited states
