论文摘要
我们在$ \ tt {powheg〜box} $的框架内，提出了完整的electroweak $ h+2〜 \ text {jets} $生产过程，这是一种公共工具，用于匹配固定订单扰动计算与Parton淋浴生成器。我们的实施允许同时描述向量 - 玻璃融合和Higgsstrahlung的贡献。 NLO-QCD和Electroweak校正分别考虑到QCD和QED淋浴。发现固定顺序QCD和Electroweak校正的大小是中等的，但取决于考虑的选择切割。 QCD淋浴效果稍微修改了NLO-QCD预测，对于非标记喷气机的分布最为明显。 QED淋浴效果的影响很小。
We present an implementation of the full electroweak $H+2~\text{jets}$ production process at hadron colliders in the framework of the $\tt{POWHEG~BOX}$, a public tool for the matching of fixed-order perturbative calculations with parton shower generators. Our implementation allows for the simultaneous description of vector-boson fusion and Higgsstrahlung contributions. NLO-QCD and electroweak corrections are taken into account and matched to QCD and QED showers, respectively. The size of the fixed-order QCD and electroweak corrections is found to be moderate, but dependent on the considered selection cuts. QCD shower effects slightly modify the NLO-QCD predictions and are most pronounced for distributions of non-tagging jets. The impact of QED shower effects is small.
