S. Jadach, A. Kusina, M. Skrzypek, M. Slawinska

摘要:

本文以LHC重玻色子产生过程为例,提出了在初始状态蒙特卡罗部分子簇射(硬过程部分)中加入QCD非线性光学修正的新方法。尽管简化模型的过程中,数值结果证明,新方法的基本概念正确的工作在Monte Carlo部分子簇射事件发生器的数值环境。所提出的方法是一种替代成熟的方法,MC@NLO和POWHEG。文中还讨论了新方法的一些改进,使之具有更好的计算机CPU时间效率。

英文摘要:

The new methodology of adding QCD NLO corrections in the initial state Monte Carlo parton shower (hard process part) is presented using process of the heavy boson production at the LHC as an example. Despite the simplified model of the process, presented numerical results prove that the basic concept of the new methodology works correctly in the numerical environment of the Monte Carlo parton shower event generator. The presented method is an alternative to the well established methods, MC@NLO and POWHEG. Refinements of the new method with better computer CPU time efficiency are also discussed.
