FINAL STARE INTERACTION ENHANCEMENT EFFECT ON THE NEAR THRESHOLD pp-bar SYSTEM IN B~±→pp-barπ~± DECAY

摘要

We discuss the low-mass enhancement effect in the baryon–antibaryon invariant mass in three-body baryonic B decays using final state interactions in the framework of Regge theory. We show that the rescattering between baryonic pair can reproduce the observed mass spectrum.
