A CONJECTURED PLANAR PATTERN FOR THE LEADING STATES OF BARYONIUM
Geoffrey F. Chew · eScholarship (California Digital Library) · 1976
Two natural~parity trajectories, with isospin degeneracy as we~ as exchange degeneracy, are shown able to account for most of the available evidence concerning states that communicate preferentially with baryon-antibaryon channels.It is suggested tba t th' 5' (1255) ms.y be the ground state of this spectrum.Duality arguments bave.since1968 anticipated a family of mesons that couple predaninantly to baryon-antibaryon channels (1].A variety of experimental results bas lent support to the existence of ** such mesons, which we here c:l:lar&cterize as states of ''ba.ryonium," but the overall phencmenologioa.lpicture bas remained fragmentary.We here propose two leading baryonium trajectories of a "planar" character, which seem capible of encomp:~ssing a large proportion of the present experimental information.Many predictions are implied by thls pro:poss.l."""
