AI总结:

VBFNLO 3.0是用于模拟电弱玻色子过程的部分子级蒙特卡洛程序,新增BLHA接口、T矩阵幺正化、多种NLO过程及OpenMPI并行化,提升了对撞机物理模拟能力。

摘要:

VBFNLO是一个灵活的部分子级蒙特卡洛程序,用于模拟强子对撞机中强耦合常数下次领头阶(NLO)的矢量玻色子融合(VBF)、QCD诱导的单和双矢量玻色子产生加两个喷注、双和三个矢量玻色子产生(加喷注)过程,以及单圈水平的胶子融合产生希格斯玻色子加两个喷注过程。对于新版本——3.0版——已包含几项重大改进。根据Binoth Les Houches协议(BLHA)为所有VBF和双/三玻色子过程(包括全轻子衰变)添加了接口。对于所有影响矢量玻色子散射(VBS)过程的维度-8算子,已实现修正的T矩阵幺正化程序。已添加了几个新的产生过程,即NLO的VBS $Zγjj$和$γγjj$过程,NLO的$γγjj$、$WWj$和$ZZj$产生(包括圈诱导的胶子融合贡献),以及LO的胶子融合单圈诱导的$Φjjj$($Φ$是CP偶或CP奇标量玻色子)过程,保留了完整的顶夸克质量依赖性。最后,代码已使用OpenMPI并行化。

英文摘要:

VBFNLO is a flexible parton level Monte Carlo program for the simulation of vector boson fusion (VBF), QCD-induced single and double vector boson production plus two jets, and double and triple vector boson production (plus jet) in hadronic collisions at next-to-leading order (NLO) in the strong coupling constant, as well as Higgs boson plus two jet production via gluon fusion at the one-loop level. For the new version -- Version 3.0 -- several major enhancements have been included. An interface according to the Binoth Les Houches Accord (BLHA) has been added for all VBF and di/tri-boson processes including fully leptonic decays. For all dimension-8 operators affecting vector boson scattering (VBS) processes, a modified T-matrix unitarization procedure has been implemented. Several new production processes have been added, namely the VBS $Zγjj$ and $γγjj$ processes at NLO, $γγjj $, $WWj$ and $ZZj$ production at NLO including the loop-induced gluon-fusion contributions and the gluon-fusion one-loop induced $Φjjj$ ($Φ$ is a CP-even or CP-odd scalar boson) process at LO, retaining the full top-mass dependence. Finally, the code has been parallelized using OpenMPI.
