论文摘要
我们建议在Madgraph5_AMC@nlo Framework $ \ sqrt {s} $ = 14 TEV中的ZZ，ZZJ和ZZJJ Productions的实现。我们通过QCD校正以领先顺序和临近领先的顺序计算这些过程，并在包括Gluon融合贡献在内的JET的横向动量中对它们的总横截面进行了理论预测。同时，我们估计他们的理论不确定性。我们使用毕5thia8讨论了在党级和强调下进行淋浴和强调的各种运动学分布光谱。为了重建类似于LHC上的事件，我们使用Atlas卡和快速检测器仿真Delphes。
We propose an implementation of ZZ, ZZj and ZZjj productions in MadGraph5_aMC@NLO framework at $\sqrt{s}$ = 14 TeV. We calculate these processes at leading order and next-to-leading order with QCD corrections and we present a theoretical prediction of their total cross sections with different cuts in transverse momentum of jets, including gluon fusion contributions. In the same time we estimate their theoretical uncertainty. We discuss the various kinematical distributions spectrums at partonic level and hadronic level applying the showering and hadronization using Pythia8. In order to reconstruct the events similar to that found at LHC, we use the ATLAS cards and the fast detector simulation Delphes.
