Abstract

A novel mechanism of H0 and strangelet production in hadronic interactions within the Gribov-Regge approach is presented. In contrast to traditional distillation approaches, here the production of multiple (strange) quark bags does not require large baryon densities or a QGP. The production cross section increases with center of mass energy. Rapidity and transverse momentum distributions of the H0 are predicted for pp collisions at Elab = 160 AGeV (SPS) and s = 200 AGeV (RHIC). The predicted total H0 multiplicities are of order of the Omega-baryon yield and can be accessed by the NA49 and the STAR experiments.
