Abstract

Recent lattice QCD calculations showed that a dNΩ similar to the deuteron with baryon number B=2 and with a small binding energy might exist. In this work we propose a hadronic molecular approach to study the dynamical properties of this exotic state. We employed a phenomenological Lagrangian approach to describe the coupling of the dNΩ to its constituents and the strong decays into conventional hadrons, dNΩ→ΛΞ and dNΩ→ΣΞ. Predictions for the sum of the decay rates are in the range of a few hundred keV. In addition, we find that the dNΩ→ΛΞ mode is dominant, preferably searched for in a future Relativistic Heavy Ion Collider (RHIC) experiment.
