Retardation effects and virtual annihilation interactions in relativistic three-body systems. (English) Zbl 1387.81258

Int. J. Theor. Phys. 57, No. 1, 238-249 (2018).
Summary: The Hamiltonian formalism of quantum field theory and the variational methods in a reformulated model have been used to investigate the influence of retardation effects or virtual annihilation interactions in relativistic three-body wave equations for scalar two particles and one antiparticle interacting via a massive or massless mediating scalar field. The results show that the inclusion of virtual annihilation interactions or retardation effects can have noticeable consequence on the three-body binding energy at strong coupling.
