论文摘要
非相关量子染色体动力学（NRQCD）分解配方是研究重夸昆翁的产生的重要方法。在本文中，我们使用NRQCD分解配方式研究了$ e^+e^ - collider的$ω_{CCC} $和$ω__{BBB} $的生产。我们正好计算流程的总和横截面，$ e^+e^ - \rightArrowγ^*/z^*\ rightArrowω__{ccc} \ bar {c} \ bar {c} \ bar {c} \ bar {c} \ bar {c} ω__{bbb} \ bar {b} \ bar {b} \ bar {b} $，在$ e^+e^ - $ colliders的领先顺序中，具有不同的能量。结果表明，很难直接在$ e^+e^ - collider上观察它们。
Non-relativistic quantum chromodynamics (NRQCD) factorization formulism is an important approach to investigate the production of the heavy quarkonium. In this paper, we study the production of the $Ω_{ccc}$ and $Ω_{bbb}$ at the $e^+e^-$ collider, using the NRQCD factorization formulism. We calculate the total and differential cross sections exactly of the processes, $e^+e^-\rightarrow γ^*/Z^*\rightarrow Ω_{ccc}\bar{c}\bar{c}\bar{c}$ and $e^+e^-\rightarrow γ^*/Z^*\rightarrow Ω_{bbb}\bar{b}\bar{b}\bar{b}$, in the leading order at the $e^+e^-$ colliders with different energies. The results show that it is hard to observe them at the $e^+e^-$ collider directly.
