摘要：

The cross-section for threshold pi(0) production in proton-proton collisions is evaluated in the framework of the covariant spectator description, The negative energy intermediate states are included non-perturbatively and seen to yield a considerably smaller contribution, when compared to perturbative treatments. A family of OBE-models with different off-shell scalar coupling is considered. (C) 1997 Elsevier Science B.V.
