论文摘要
在这项工作中，我们调查了前瞻性四轨和四元龙的光谱，即。 Baryon-Antibaryon在QCD和规则的框架中指出。考虑到维度10的非扰动贡献。数值结果表明，可能存在4个可能存在的具有质量$（7.33 \ pm0.12）$，$（7.42 \ pM0.13）$的四载臂bary液状态，$（7.68 \ pm0.17）$，$（7.76 \ pm0.12） $ 0^{++} $和$ 1^{++} $。发现相应的四副伙伴分别以$（19.41 \ pm 0.15）$，$（19.48 \ pm 0.15）$，$（19.77 \ pm 0.19）$（19.77 \ pm 0.19）$和$（19.84 \ pm 0.19）$ GEV。此外，我们还分析了$ \barξ_{bc}ξ_{bc} $和$ \barξ_{cc}ξ_{bb} $ baryonium状态的光谱，分别在$ 13.77-14.40 $ GEV和13.39-39-14.14 $ GEV的范围内。分析了可能的BARYONIUM衰减模式，希望在LHC实验中可以测量。
In this work, we investigate the spectra of the prospective tetracharm and tetrabottom baryonium, viz. the baryon-antibaryon states, in the framework of QCD sum rules. The non-perturbative contributions up to dimension 10 are taken into account. Numerical results indicate that there might exist 4 possible tetracharm baryonium states with masses $(7.33\pm0.12)$, $(7.42\pm0.13)$, $(7.68\pm0.17)$, and $(7.76\pm0.12)$ GeV for the quantum numbers of $0^{-+}$, $1^{--}$, $0^{++}$, and $1^{++}$, respectively. The corresponding tetrabottom partners are found lying respectively at $(19.41\pm 0.15)$, $(19.48\pm 0.15)$, $(19.77\pm 0.19)$ and $(19.84\pm 0.19)$ GeV. Additionally, we also analyze the spectra of the $\barΞ_{bc}Ξ_{bc}$ and $\barΞ_{cc}Ξ_{bb}$ baryonium states, which lie in the range of $13.77-14.40$ GeV and $13.39-14.14$ GeV, respectively. The possible baryonium decay modes are analyzed, which are hopefully measurable in LHC experiments.
