Numerical solution of two-body relativistic equations for the bound-state problem with confining and Coulomb potentials (Q1973498)

This paper is devoted to the numerical investigation of the behavior of mesons considering them as quark-antiquark bound-states. Their behavior is described by some three-dimensional integral equations within the framework of some relativistic potential QCD models with singularities in its kernel in the momentum space. The numerical study is carried out by generalized continuous Newton iteration methods implemented by their own computer programs called SLIPH4 and SYSINT using modified potentials to remove singularities in the Coulomb and confining potential.
