Abstract

Solutions of the two‐body Dirac equation with diagonal central potentials are investigated, both for particle–particle and particle–antiparticle cases. A detailed study of the symmetry properties of the solutions is carried out for systems composed of identical or massless particles. The Klein paradox is discussed and several solutions relevant to the study of the quarkonium are presented.

Basis (linear algebra), Anharmonicity, Propagator, Statistical and Nonlinear Physics, Function (mathematics), Lippmann–Schwinger equation, symbols.namesake, Green's function, Quantum mechanics, symbols, Wave function, Mathematical Physics, Harmonic oscillator, Mathematics
Abstract

A closed and analytical formula is given for the free Green’s function in a harmonic oscillator basis. It is very useful for solving the Lippman–Schwinger equation for the scattering of two clusters within the resonating group method formula.
