| dc.description.abstract | We discuss the effective Hamiltonian approach to fermion-antifermion bound states, which imitates its description in terms of non-relativistic potential models. This approach is the relativistic generalization of the non-relativistic potential models. In this framework, observables such as, the ground state energy and the triplet-singlet mass differene of light mesons are calculated. We use both linear and funnel potential confinements comparatively. Though the constituents of mesons basically interact through the exchange of vector bosons, we also consider the constituents as if they interact through the exchange of pure scalar bosons | en_US |
