Exact spinor-scalar bound states in a QFT with scalar interactions
Volodymyr Shpytko, Jurij Darewych
We study two-particle systems in a model quantum field theory, in which scalar particles and spinor particles interact via a mediating scalar field. The Lagrangian of the model is…

A Variational Fock-Space Treatment of Quarkonium
L. Di Leo, J. W. Darewych
The variational method and the Hamiltonian formalism of QCD are used to derive relativistic, momentum space integral equations for a quark-antiquark system with an arbitrary number…
