论文摘要
我们在这项工作中报告了$ w^+w^ - $ pairs量规玻色子在LHC的质子 - 普罗顿碰撞中与0、1和2喷气式相关的玻色子，在Mass中心的能量为14 TEV。这些过程是在标准模型中使用MADGRAPH5@AMC在标准模型中使用QCD校正的前阶（LO）和临时领导级（NLO）产生的。对于对过程的现实描述，我们将硬散射过程与Pythia8 Parton淋浴和强环化匹配。获得的事件是通过快速检测器仿真Delphes运行的，该模拟可准确地对ATLAS和CMS检测器以及执行的最终状态重建进行建模。我们根据射流横向动量P t的两次切割，J> 20 GEV和P T，J> 100 GEV分析了总横截面。我们通过在党派固定顺序和parton淋浴中呈现横向动量和速度分布来描述计算的重要数值方面。
We report in this work the production of $W^+W^-$ pairs gauge bosons associated with 0, 1 and 2 jets in proton-proton collisions at LHC with an energy of 14 TeV in the center of mass. These processes are produced at leading-order (LO) and next-to-leading-order (NLO) with QCD corrections in the standard model, using MadGraph5@aMC. For a realistic description of the processes, we match the hard scattering processes with Pythia8 parton showering and hadronization. The obtained events are run through the fast detector simulation, Delphes, which serves to accurately model the ATLAS and CMS detectors and the final state reconstructions that are performed. We analyze the total cross sections according on two cuts in jet transverse momentum p T,j > 20 GeV and p T,j > 100 GeV. We describe the important numerical aspects of our calculations by presenting transverse momentum and rapidity distributions at partonic fixed order and at parton shower for both W and the $W^+W^-$ pair.
