Relativistic two-body calculation of -mesons radiative decays
A. Barducci, R. Giachetti, E. Sorace
This paper is a prosecution of a previous work where we presented a unified two-fermion covariant scheme which produced very precise results for the masses of light and heavy meson…
Relativistic two fermion treatment of hyperfine transitions
A. Barducci, R. Giachetti, E. Sorace
A system of two fermions with different masses and interacting by the Coulomb potential is presented in a completely covariant framework. The spin-spin interaction, including the a…
Unified covariant treatment of hyperfine splitting for heavy and light mesons
R. Giachetti, E. Sorace
This paper aims at proving the fundamental role of a relativistic formulation for quarkonia models. We present a completely covariant description of a two-quark system interacting…
Two fermion relativistic bound states: hyperfine shifts
R. Giachetti, E. Sorace
We discuss the hyperfine shifts of the Positronium levels in a relativistic framework, starting from a two fermion wave equation where, in addition to the Coulomb potential, the ma…
