Light baryonium spectrum

We evaluate the light baryonium spectrum, viz. baryon-antibaryon states, in framework of QCD sum rules. The nonperturbative contributions up to dimension 12 are taken into account. Numerical results indicate that there might exist eight possible i.e. $p\ensuremath{-}\overline{p}$, $\mathrm{\ensuremath{\Lambda}}\ensuremath{-}\overline{\mathrm{\ensuremath{\Lambda}}}$, $\mathrm{\ensuremath{\Sigma}}\ensuremath{-}\overline{\mathrm{\ensuremath{\Sigma}}}$, and $\mathrm{\ensuremath{\Xi}}\ensuremath{-}\overline{\mathrm{\ensuremath{\Xi}}}$ with quantum numbers ${0}^{\ensuremath{-}+}$ ${1}^{\ensuremath{-}\ensuremath{-}}$. For their masses found above corresponding dibaryon thresholds, while $p\ensuremath{-}\overline{p}$ states not. decay modes analyzed, which hopefully measurable BESIII, BELLEII, LHCb experiments.
