13 TeV pp collisions, Top type, MADGRAPH/PY6 generator: tev13pp_mg5_ttbar_njet

top+N-jet-quark production (ttbar+N jet) at LO QCD +PS. Madgraph5 with Pythia6. Version MG5_aMC v2_3_2_2. All top decays. PYTHIA6 used for parton_shower and hadronization. PDF is 230000 (nn23lo1). See more details in the log file. Note: Number of events and cross section in the sample was estimated from a single file. The number of events varies from file to file. You need to run over all files to calculate correctly luminosity.

顶夸克-反顶夸克对伴随N个喷注的产生过程（ttbar+N喷注），基于领头阶量子色动力学（Leading Order QCD, LO QCD）并结合部分子喷注（Parton Shower, PS）模拟。本模拟采用MadGraph5配合Pythia6完成，版本为MG5_aMC v2_3_2_2。样本涵盖所有顶夸克衰变道。PYTHIA6用于实现部分子喷注演化与强子化过程。部分子分布函数（Parton Distribution Function, PDF）选用230000（nn23lo1）。更多细节请参阅日志文件。备注：该样本的事件数与截面数值仅通过单个文件估算得到，不同文件的事件数存在波动。若需准确计算积分亮度，需遍历全部样本文件进行统计。
