蒙特卡罗积分器HAWK提供了在矢量-玻色子聚变和Higgs应变中强子对撞机上Higgs产生的精确预测，即在Higgs玻色子附加到WeaK玻色子的生产过程中。全差分预测包括完整的QCD和弱电次导数阶修正。计划概要计划标题：HAWK，2.0版目录识别符：AEWT_v1_0计划概要URL:http://cpc.cs.qub.ac.uk/summaries/AEWT_v1_0.htmlProgram可从：爱尔兰贝尔法斯特女王大学CPC程序库获得许可条款：标准CPC许可证，http://cpc.cs.qub.ac.uk/licence/licence.htmlNo.分布式程序中的行数，包括测试数据等：132878号分布式程序中的字节数，包括测试数据等。分布格式：tar.gz编程语言：Fortran 77，Fortran 90。计算机：任何装有Fortran 90编译器的计算机。操作系统：LINUX，Mac OS。RAM：不到1 GB分类：4.4，11.1，11.2。外部例程：LHAPDF(https://www.hepforge.org/downloads/lhapdf).Nature of Problem：如参考文献所述，在大型强子对撞机上矢量-玻色子聚变和希格斯辐射中希格斯-玻色子产生的截面和微分分布的精确计算。[1-3].求解方法：多道蒙特卡罗积分微扰矩阵元，包括基于Feynman图解计算的高阶QCD和电弱修正.限制：对于矢量-玻色子融合，只支持希格斯-玻色子衰变成一对无质量单态.对于希格斯辐射，衰变产物不受支持，而希格斯玻色子可以脱离壳层。运行时间：在单个核上几个小时内就可以获得有意义的结果。参考文献：M.Ciccolini，A.Denner，S.Dittmaier，Phys.莱特牧师。99(2007年)161803[arxiv：0707.0381.[hep-ph].[2]M.Ciccolini，A.Denner，S.Dittmaier，Phys.Rev.D77(2008年)013002[arxiv：0710.4749.[hep-ph]].[3]A.Denner，S.Dittmaier，S.Kallweit和A.Mück，J.高能物理.第1203(2012)075[arxiv：1112.5142.[hep-ph]]
The Monte Carlo integratorHAWKprovides precision predictions for Higgs production at hadron colliders in vector-boson fusion and Higgs strahlung, i.e. in production processes where theHiggs boson isAttached toWeaKbosons. The fully differential predictions include the full QCD and electroweak next-to-leading-order corrections. Results are computed as integrated cross sections and as binned distributions for important hadron-collider observables.Program summaryProgram title:HAWK, version 2.0Catalogue identifier:AEWT_v1_0Program summary URL:http://cpc.cs.qub.ac.uk/summaries/AEWT_v1_0.htmlProgram obtainable from:CPC Program Library, Queen’s University, Belfast, N.

[1–3].Solution method:Multi-channel Monte Carlo integration of perturbative matrix elements including higher-order QCD and electroweak corrections which are based on a Feynman-diagrammatic calculation.Restrictions:For vector-boson fusion, only the Higgs-boson decay into a pair of massless singlets is supported. For Higgs strahlung, decay products are not supported, while the Higgs boson can be off shell.Running time:Meaningful results can be obtained within a few hours on a single core. The statistical uncertainty of the results typically improves with the square root of the run time.References:[1]M. Ciccolini, A. Denner, S. Dittmaier, Phys. Rev.
