论文摘要
我们提出了Higgs Boson生产的全阶预测以及至少一台喷气式飞机，它们准确地以$ \ hat s/| p_ \ perp |^2 $领先对数。我们的计算包括对数部分中所有订单的顶部和底部夸克质量依赖性，以及在树级匹配中的最高可用顺序。该计算是在高能喷气机（HEJ）框架中实施的。这是第一个使用$ \ log（\ hat s）$重新召集的横截面，并与固定订单相匹配，以便仅需要一台喷气机，我们的结果还扩展了带有两个或更多喷气机的进程的重新点亮区域。这是可能的，因为重新召集是在相空间中明确执行的。我们将新计算的结果与LHC数据和次要领先的顺序预测进行了比较，并在关键分布的形状中找到对数校正的数值显着影响，该影响在横截面的归一化之后保留。
We present all-order predictions for Higgs boson production plus at least one jet which are accurate to leading logarithm in $\hat s/|p_\perp|^2$. Our calculation includes full top and bottom quark mass dependence at all orders in the logarithmic part, and to highest available order in the tree-level matching. The calculation is implemented in the framework of High Energy Jets (HEJ). This is the first cross section calculated with $\log(\hat s)$ resummation and matched to fixed order for a process requiring just one jet, and our results also extend the region of resummation for processes with two jets or more. This is possible because the resummation is performed explicitly in phase space. We compare the results of our new calculation to LHC data and to next-to-leading order predictions and find a numerically significant impact of the logarithmic corrections in the shape of key distributions, which remains after normalisation of the cross section.
