论文摘要
我们报告了重型二比元的首次晶格QCD研究，其中所有六个夸克都具有底部（美感）风味。执行最先进的晶格QCD计算，我们找到了明确的证据，这些证据是在$^1s_0 $ channel中的$^1S_0 $通道中的$ω_________________________________________________________{ $ -81（_ { - 16}^{+14}）$ MEV。有了如此深的结合，库仑排斥仅作为对参数化强势的基态波函数的扰动，并且只能将强结合仅移动几个百分比。考虑到标量通道是单个调味二生章的最束缚的通道，我们得出结论，这种状态是可见宇宙中最深层绑定的二巴里亚人。
We report the first lattice QCD study of the heavy dibaryons in which all six quarks have the bottom (beauty) flavor. Performing a state-of-the-art lattice QCD calculation we find clear evidence for a deeply bound $Ω_{bbb}$-$Ω_{bbb}$ dibaryon in the $^1S_0$ channel, as a pole singularity in the $S$-wave $Ω_{bbb}$-$Ω_{bbb}$ scattering amplitude with a binding energy $-81(_{-16}^{+14})$ MeV. With such a deep binding, Coulomb repulsion serves only as a perturbation on the ground state wave function of the parameterized strong potential and may shift the strong binding only by a few percent. Considering the scalar channel to be the most bound for single flavored dibaryons, we conclude this state is the heaviest possible most deeply bound dibaryon in the visible universe.
