论文摘要
在这项工作中，我们建议在此过程中调查$ d_ {nΩ} $ dibaryon生产，$ k^ - p \ p \ rightarrow d_ {nΩ} \barξ^0 $，通过使用Kaon Beam的典型动量为10 GEV，大约为10 GEV，可以在Compass，Oka@U-70和Sps@cern@cers@cern@compass，Oka@u-70和cern@cern。估计了$ k^ - p \ rightarrow d_ {nΩ} \ bar配给0 $的横截面，尤其是，评估横截面的大小为$ p_k = 20 $ gev的数百个纳米果。 Considering that $d_{NΩ}$ dibaryon dominantly decay into $ΞΛ$ and $ΞΣ$, we also estimate the cross sections for $K^- p \to Ξ^0 Λ\barΞ^0$ and $K^- p \to Ξ^- Σ^+ \barΞ^0$, where the $d_{NΩ}$ dibaryon can be observed in the invariant mass distributions $ξ^0λ$和$ξ^ - σ^+ $的$。
In this work, we propose to investigate the $d_{NΩ}$ dibaryon production in the process $K^- p \rightarrow d_{NΩ} \barΞ^0$ 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 $K^- p \rightarrow d_{NΩ} \barΞ^0$ 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 $d_{NΩ}$ dibaryon dominantly decay into $ΞΛ$ and $ΞΣ$, we also estimate the cross sections for $K^- p \to Ξ^0 Λ\barΞ^0$ and $K^- p \to Ξ^- Σ^+ \barΞ^0$, where the $d_{NΩ}$ dibaryon can be observed in the invariant mass distributions of $Ξ^0 Λ$ and $Ξ^- Σ^+ $, respectively.
