Production of dibaryon $d_{N\Omega }$ in kaon induced reactions

Abstract

In this work, we propose to investigate the $d_{N\Omega }$ dibaryon production in the process $K^{-}p\to d_{N\Omega }{\bar{\Xi }}^0$ by utilizing the kaon beam with the typical momentum to be around 10 GeV, which may be available at COMPASS, OKA@U-70 and SPS@CERN. The cross sections for $K^{-}p\to d_{N\Omega }{\bar{\Xi }}^0$ are estimated and in particular, the magnitude of the cross sections are evaluated to be several hundreds nanobarn at $P_K=20$ GeV. Considering that $d_{N\Omega }$ dibaryon dominantly decay into $\Xi \Lambda$ and $\Xi \Sigma$, we also estimate the cross sections for $K^{-}p\to {\Xi }^0\Lambda {\bar{\Xi }}^0$ and $K^{-}p\to {\Xi }^{-}{\Sigma }^{+}{\bar{\Xi }}^0$, where the $d_{N\Omega }$ dibaryon can be observed in the invariant mass distributions of ${\Xi }^0\Lambda$ and ${\Xi }^{-}{\Sigma }^{+}$, respectively.
