In contrast to Δ(Kp), Δ(pp) shows a distinct departure from a single power behaviour in Plab(v or s), characteristic of the ω, ρ exchange. It can be accounted for quantitatively by adding a lower lying trajectory, which is identified as a baryonium. Its intercept and residue parameters are compared with other estimates of baryonium exchange.
