论文摘要
我们介绍了在Gluon融合中对Higgs-Boson对产生的NLO QCD校正的计算，包括标准模型有效磁场理论（SMEFT）中异常耦合的影响。我们研究了EFT扩展在$ 1/λ$中的不同截短选项和双操作员插入的效果，无论是在总横截面水平上以及Higgs-Boson对不变质量的分布，以$ \ sqrt {s} = 13 $ tev。 NLO校正在$ \ texttt {powheg-box-v2} $ framework中的生成器$ \ texttt {gghh_smeft} $中实现。
We present a calculation of the NLO QCD corrections for Higgs-boson pair production in gluon fusion including effects of anomalous couplings within Standard Model Effective Field Theory (SMEFT). We study effects of different truncation options of the EFT expansion in $1/Λ$ and of double operator insertions, both at total cross-section level as well as for the distribution of the invariant mass of the Higgs-boson pair, at $\sqrt{s}=13$ TeV. The NLO corrections are implemented in the generator $\texttt{ggHH_SMEFT}$ in the $\texttt{Powheg-Box-V2}$ framework.
