Abstract
The cross-section for threshold pi(0) production in proton-proton coll isions is evaluated in the framework of the covariant spectator descri ption, The negative energy intermediate states are included non-pertur batively and seen to yield a considerably smaller contribution, when c ompared to perturbative treatments. A family of OBE-models with differ ent off-shell scalar coupling is considered. (C) 1997 Elsevier Science B.V.
