论文摘要
我们在LHC的Di-Lepton Decay通道中报告了我们最近计算的计算$ t \ bar {t} b \ bar {b} $进程。我们的结果考虑了完整的$ PP \ to e^+ν_eμ^ - \barν_μb\ bar {b} b \ bar {b} $过程的NLO QCD校正，并包括所有双重，单一和非呼吸贡献。我们研究校正的大小及其相关的理论不确定性。我们还简要评论了不同的$ B $ JET定义对我们结果的影响。
We report on our recent calculation for the off-shell $t\bar{t}b\bar{b}$ process in the di-lepton decay channel at the LHC. Our results take into account NLO QCD corrections for the complete $pp\to e^+ν_eμ^- \barν_μb\bar{b}b\bar{b}$ process, and include all double, single and non-resonant contributions. We investigate the size of the corrections and their associated theoretical uncertainties. We also briefly comment on the impact of different $b$ jet definitions on our results.
