In this paper, we study the associated production of prompt mesons and bosons in the improved color evaporation model using the high-energy factorization as it is formulated in the parton Reggeization approach. The last one is based on the modified Kimber–Martin–Ryskin–Watt model for unintegrated parton distribution functions and the effective field theory of Reggeized gluons and quarks, suggested by Lipatov. We predict cross-section for associated and hadroproduction via the single and double parton scattering mechanisms using the set of model parameters which has been obtained early for description of single and double prompt production at the LHC energies. The numerical calculations are realized using the Monte Carlo event generator KaTie. The calculation results are compared with the data at the energies TeV and 8TeV and we make predictions for the energy TeV for plus and plus associated production at TeV and 13TeV.

在本文中,我们研究了提示的关联产生介子和改进的颜色蒸发模型中的玻色子使用高能分解,因为它是在部分子调整方法中制定的。最后一个模型基于 Lipatov 提出的未积分部分子分布函数的修正 Kimber-Martin-Ryskin-Watt 模型以及 Reggeized 胶子和夸克的有效场理论。我们预测相关的横截面和使用早期为描述单提示和双提示而获得的模型参数集,通过单部分子散射机制和双部分子散射机制进行粒子生产大型强子对撞机(LHC)能量的生产。数值计算是使用蒙特卡罗事件生成器KaTie 实现的。将计算结果与能量处的数据进行比较TeV 和 8TeV,我们对能量进行预测TeV 为加和加相关生产在TeV 和 13TeV。
