$$d_{N \Omega }$$ production in $$\Omega d$$ scattering process

Abstract In the present work, we propose to investigate the production of $$d_{N \Omega }$$ d N Ω in the $$\Omega ^{-} d \rightarrow p d_{N \Omega }^-$$ Ω - d → p d N Ω - process by utilizing an effective Lagrangian approach, where $$d_{N \Omega }$$ d N Ω is identified as $$N\Omega $$ N Ω bound state with the binding energy $$E_{b}=2.46$$ E b = 2.46 MeV. Experimentally, the J-PARC hadron facility proposed to investigate the $$K^{-}p \rightarrow \Omega ^{-} \bar{K}^{(*)0} K^{+}$$ K - p → Ω - K ¯ ( ∗ ) 0 K + process, which is expected to yield an $$\Omega $$ Ω beam with the momentum of approximately 3 GeV. Additionally, theoretical studies of the $$\psi (2S) \rightarrow \Omega ^{-} \bar{\Omega }^{+}$$ ψ ( 2 S ) → Ω - Ω ¯ + process at BESIII provided an $$\Omega $$ Ω beam with the momentum of 774 MeV. Considering these two potential $$\Omega $$ Ω beam sources, our estimations show that for the $$\Omega ^{-} d \rightarrow p d_{N \Omega }^-$$ Ω - d → p d
