$\Omega d$ bound state

Abstract

The lattice QCD analyses of the HAL QCD Collaboration predicts a strongly attractive potential in the $\Omega N$ ${}^5{S}_2$ channel which supports a bound state. In this paper we show that this $\Omega N$ channel together with the $NN$ ${}^3{S}_1$ channel give rise to a $\Omega d$ bound state in the state with maximal spin $(I,J^P)=(0,5/2^{+})$ with a binding energy of $\sim$ 17 MeV.
