Towards the decay properties of deuteron-like state $d_{N\Omega }$

Abstract

Recent lattice QCD calculations showed that a $d_{N\Omega }$ dibaryon state similar to the deuteron with small binding energy may exist. In this work we propose a hadronic molecular approach to study the dynamical properties of this exotic state. We use a phenomenological Lagrangian approach to describe the coupling of the $d_{N\Omega }$ state to its constituents and the decays into conventional hadrons, $d_{N\Omega }\to \Lambda \Xi$ and $d_{N\Omega }\to \Sigma \Xi$. Predictions for the sum of the decay rates are in the range of a few hundred keV. In addition, we find that the $d_{N\Omega }\to \Lambda \Xi$ mode is dominant, preferably searched for in a future RHIC experiment.
