论文摘要
在此程序中，我们为在LHC的dilepton decay decay频道中使用$ \ sqrt {s} = 13 $ tev介绍了$ t \ bar {t} b \ bar {b} $的完整NLO QCD校正的预测。考虑所有完整的外壳效果，进行计算。此外，详细研究了此过程的各种不确定性来源。然后，我们将这些预测与实验测量进行比较。我们还调查了$ b $ QUARK启动子过程的影响。
In this proceeding we present predictions for the complete NLO QCD corrections to the production of $t\bar{t}b\bar{b}$ in the dilepton decay channel of the top quark at the LHC with $\sqrt{s}=13$ TeV. The calculation is performed considering all the full off-shell effects. Moreover, the various sources of uncertainty for this process are studied in detail. We then compare these predictions to experimental measurements. We additionally investigate the impact of the $b$-quark initiated subprocesses.
