论文摘要
最近，HAL QCD合作报告了lattice QCD模拟的$ω-ω$和$ n-ω$相互作用的潜力。基于这些结果，预测$nΩ$（$^5s_2 $）和$ω$（$^1S_0 $）的绑定状态被预测，具有约为几meV的绑定能量。此外，$ N-ω$ HBT相关功能还通过Star协作以及Alice的合作来衡量。这些结果提供了动态信息，无论是否存在$ω$ -Dibaryons在交互方面。检测$ω$ -Dibaryons的另一个必要点是实验环境，可以在系统中产生和生存。在这种情况下，至少有两个必要的条件来限制$ω$ -Dibaryons的生产概率，即一种是形成绑定状态的必要的短程吸引人的相互作用，而另一种是诸如重型离子碰撞之类的实验环境，提供了足够丰富的核子的陌生性和多重性。在这封信中，使用了$ω-ω$和$ω-$核子的互动电位，该固定QCD模拟被用来获得$ωΩ$（$^1S_0 $）和$nΩ$（$^5S_2 $）波函数，然后使用$ω$ -Dibaryons的繁殖机制来估计，然后使用$ω$ -Dibaryons的生产力。 $ \ sqrt {s_ {nn}} = $ 200 GEV和2.76 TEV。
Recently the HAL QCD Collaboration reported the $Ω-Ω$ and $N-Ω$ interaction potentials by the lattice QCD simulations. Based on these results, $NΩ$ ($^5S_2$) and $ΩΩ$ ($^1S_0$) bound states were predicted with the binding energy about a few MeV. In addition, $N-Ω$ HBT correlation function was also measured by the STAR Collaboration as well as the ALICE Collaboration. These results provide dynamical information whether or not $Ω$-dibaryons exist in the interaction aspects. Another necessary point for the detection of $Ω$-dibaryons is the experimental environment where the bound state could be produced and survived in the system. In this context, there are at least two necessary conditions to constrain the production probability of $Ω$-dibaryons, i.e. the one is the necessary short-range attractive interaction to form the bound state and the another is the experimental environment such as heavy-ion collision provides abundant enough strangeness and multiplicity of nucleons. In this Letter the $Ω-Ω$ and $Ω-$nucleon interaction potentials by the lattice QCD simulations were employed to obtain $ΩΩ$ ($^1S_0$) and $NΩ$ ($^5S_2$) wave functions, and then the productions of $Ω$-dibaryons were estimated by using of a dynamical coalescence mechanism for the relativistic heavy-ion collisions at $\sqrt{s_{NN}} = $ 200 GeV and 2.76 TeV.
