摘要In this paper we derive the Theta production cross section in high energy proton-proton collisions in the relativistic framework through using effective hadronic couplings. Both the nucleon and N* (1710) propagations are taken into account in the intermediate states. The one pi and one rho exchange mechanisms are considered and the commonly accepted coupling constants and form factors are used in the calculation. We find that rho exchange is dominant in these processes and the N*(1710) propagation in the intermediate state is important,which increases the Theta production cross section by a factor of a few tens at center of mass energy 4GeV.
