Description

The hyperfine splitting of the ground state of baryonium is calculated using parameters derived solely from baryon data. The model used employs a harmonic-oscillator potential suitably modified to describe an attractive potential at short range (Coulomb-type piece derived from quantum chromodynamics) and deviations from the harmonic-oscillator form at large distances. Comparisons with other theoretical calculations and experimental results are made. The hyperfine levels computed in this paper are in close agreement with those derived using a linear plus Coulomb potential
