论文摘要
在文章中，我们通过Parton Reggeization方法研究了改进的颜色蒸发模型中的单一和$ J/ψ$ HADRRODUFUCT。最后一个是基于$ k_t $ - 多重型运动学中的硬过程，金伯 - 马丁 - ryskin-watt模型，用于未整合的parton分布函数，以及L.N.提出的有效的gezied Gluons and Quarks和Quarks的现场理论。 Lipatov。我们比较了$ j/ψ$生产中单个和双方散射机制的贡献。使用Monte-Carlo事件发生器Katie实现数值计算。
In the article, we study single and pair $J/ψ$ hadroproduction in the Improved Color Evaporation Model via the Parton Reggeization Approach. The last one is based on $k_T$-factorization of hard processes in multi-Regge kinematics, the Kimber-Martin-Ryskin-Watt model for unintegrated parton distribution functions, and the effective field theory of Reggezied gluons and quarks, suggested by L.N. Lipatov. We compare contributions from the single and double parton scattering mechanisms in the pair $J/ψ$ production. The numerical calculations are realized using the Monte-Carlo event generator KaTie.
