VBFNLO是一个完全灵活的部分级蒙特卡罗程序，用于模拟强耦合常数次领先阶强子碰撞中的矢量玻色子聚变，双矢量和三矢量玻色子产生。VBFNLO包括希格斯和矢量玻色子衰变，具有完全的自旋相关和所有的脱壳效应。此外，VBFNLO通过与两个喷流相关的胶子聚变，在一阶单环水平上实现了cp -偶数和cp -奇数希格斯玻色子，在一般的双希格斯双重态模型中具有完全的顶夸克和底夸克质量依赖。标准模型物理之外产生的各种效应被用于选定的过程。这包括希格斯玻色子和矢量玻色子的异常耦合以及一个扭曲的无希格斯额外维度模型。该程序提供了为领先顺序的所有可用过程生成Les Houches Accord事件文件的可能性。项目摘要项目名称：vbfnlocatalator标识符：aedo_v1_0项目摘要URL: http://cpc.cs.qub.ac.uk/summaries/AEDO_v1_0.htmlProgram可从：CPC项目图书馆，女王大学，贝尔法斯特，N.爱尔兰许可条款：GPL版本2号。分布式程序的行数，包括测试数据等：339218分布式程序的字节数，包括测试数据等：2620847分发格式：tar。编程语言：Fortran，部分为c++计算机：操作系统：Linux，也可以在其他系统上工作分类：11.1,11.2外部例程：可选Les Houches Accord PDF接口库和GNU科学库问题性质：为了解决首阶计算中固有的大规模依赖，并量化由部子分布函数确定中的不确定性引起的截面误差，有必要包括NLO修正。此外，每当需要对衰变产物和/或已识别的射流进行严格削减时，就会出现一个问题，即为包含生产截面确定的尺度依赖性和k因子（定义为NLO与LO截面的比率）是否对感兴趣的搜索区域有效。解决方法：该问题最好通过在完全灵活的NLO部分级蒙特卡罗程序中实现单回路QCD校正来解决，其中可以指定任意切割以及各种尺度选择。此外，任何当前可用的部分分布函数集都可以通过LHAPDF库使用。运行时间：取决于所研究的过程。通常从几分钟到几小时不等。(C) 2009 Elsevier B.V.版权所有
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- and bottom-quark mass dependence in a generic two-Higgs-doublet model. A variety of effects arising from beyond the Standard Model physics are implemented for selected processes. This includes anomalous couplings of Higgs and vector bosons and a Warped Higgsless extra dimension model. The program offers the possibility to generate Les Houches Accord event files for all processes available at leading order.Program summaryProgram title: VBFNLOCatalogue identifier: AEDO_v1_0Program summary URL: http://cpc.cs.qub.ac.uk/summaries/AEDO_v1_0.htmlProgram obtainable from: CPC Program Library, Queen's University, Belfast, N.

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 are valid for the search region one is interested in.Solution method: The problem is best addressed by implementing the one-loop QCD corrections in a fully flexible NLO parton-level Monte Carlo program, where arbitrary cuts can be specified as well as various scale choices. In addition, any currently available parton distribution function set can be used through the LHAPDF library.Running time: Depending on the process studied. Usually from minutes to hours.
