Dirac equation in the confining SU(3)-Yang-Mills field and relativistic effects in charmonium spectrum
Yu. P. Goncharov
Abstract
The recently obtained solutions of the Dirac equation in the confining SU(3)-Yang-Mills field in Minkowski spacetime are applied to describe the energy spectrum of charmonium. The nonrelativistic limit is considered for the relativistic effects to be estimated in a self-consistent way and it is shown that the given effects could be extremely important for both the energy spectrum and the confinement mechanism.
