In this paper, we give a brief review of recent theoretical studies of double prompt J/ψ production at the FNAL Tevatron and the CERN LHC, to which both single- and double-parton-scattering processes contribute. In single parton scattering, we mainly present the results computed within the framework of non-relativistic quantum chromodynamics factorization combined with one of the two approaches to describe the parton inside the (anti)proton, the collinear parton model and the parton Reggeization approach. The contributions from double parton scattering calculated with different values of σeff are also discussed. We conclude that, in double prompt J/ψ hadroproduction, there remain some differences between theoretical predictions and experimental measurements.

强子对撞机的双即时 J/ψ 产生

在本文中，我们简要回顾了最近的双提示理论研究。Ĵ/ψFNAL Tevatron 和 CERN LHC 的生产，单子和双子散射过程都有贡献。在单部分子散射中，我们主要展示了在非相对论量子色动力学分解的框架内结合描述（反）质子内部部分子的两种方法之一，共线部分子模型和部分子正则化方法中的计算结果。用不同的值计算的双部分散射的贡献σ效果也进行了讨论。我们得出结论，在双重提示下Ĵ/ψ氢生产，理论预测和实验测量之间仍然存在一些差异。
