在这项工作中，我们建议利用典型动量在10GeV左右的Kaon束流，在COMPASS，OKA@U-70和SPS@CERN上，研究K^-p右行dN欧米茄过程中双重子的产生。估算了K^-p右目标d_(N\Omega)\bar的截面，特别是在$P_K=20$GeV时，截面的量级为几百纳米量级。考虑到双重子主要衰变为兰姆达和西格玛，我们还估算了双重子的截面，其中双重子分别存在于质量不变的兰姆达和西格玛中。本作品的内容可在知识共享署名3.0许可证的条款下使用。任何这部作品的进一步传播都必须保持作者(S)的署名和作品的标题、期刊引文和DOI。本文由SCOAP3资助，由中国物理学会、中国科学院高能物理研究所、中国科学院近代物理研究所和IOP出版有限公司授权出版。
In this work, we propose to investigate the $d_{N\Omega}$ dibaryon production in the process $K^- p \rightarrow d_{N\Omega} \bar{\Xi}^0$ 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 $K^- p \rightarrow d_{N\Omega} \bar{\Xi}^0$ 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.
