Vbfnlo: A parton level Monte Carlo for processes with electroweak bosons

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract Vbfnlo is a fully flexible parton level Monte Carlo program for the simulation of vector boson fusion, double and triple vector boson production in hadronic collisions at next-to-leading order in the strong coupling constant. Vbfnlo includes Higgs and vector boson decays with full spin correlations and all off-shell effects. In addition, Vbfnlo implements CP-even and CP-odd Higgs boson via gluon fusion, associated with two jets, at the leading-order one-loop level with the full top- a... Title of program: VBFNLO Catalogue Id: AEDO_v1_0 Nature of problem To resolve the large scale dependence inherent in leading order calculations and to quantify the cross section error induced by uncertainties in the determination of parton distribution functions, it is necessary to include NLO corrections. Moreover, whenever stringent cuts are required on decay products and/or identified jets the question arises whether the scale dependence and a k-factor, defined as the ratio of NLO to LO cross section, determined for the inclusive production cross sections ar ...

摘要：Vbfnlo是一款完全灵活的部分子级（parton level）蒙特卡洛程序，用于强子对撞中矢量玻色子融合、双矢量玻色子及三矢量玻色子产生过程的模拟，计算精度为强耦合常数下的次领头阶（next-to-leading order, NLO）。Vbfnlo可模拟希格斯玻色子与矢量玻色子的衰变过程，完整保留自旋关联效应与所有离壳（off-shell）效应。此外，Vbfnlo还实现了通过胶子聚变产生的CP偶（CP-even）与CP奇（CP-odd）希格斯玻色子（伴随双喷注），采用领头阶单圈精度并完整考虑顶夸克相关效应（原文此处内容截断）。

问题本质：为解决领头阶（leading order, LO）计算中固有的大标度依赖性，并量化由子部分布函数（parton distribution functions）测定不确定性引发的截面误差，需纳入次领头阶修正。此外，当对衰变产物和/或已识别喷注施加严格运动学截断时，会产生如下疑问：针对总产生截面确定的标度依赖性，以及定义为次领头阶与领头阶截面比值的k因子，是否适用于受限相空间的产生过程（原文此处内容截断）？
