我们提出了所有的订单预测希格斯玻色子生产加上至少一个喷气机是准确的领先对数。我们的计算包括完整的顶夸克和底夸克的质量依赖在对数部分的所有订单，并在树级匹配的最高可用顺序。计算是在高能射流（HEJ）的框架内进行的。这是第一个用log（）重定计算的截面，并且对于只需要一个射流的过程，该截面与固定阶数相匹配，并且我们的结果还扩展了具有两个或更多射流的过程的重定区域。这是可能的，因为在相空间中显式地执行重新表示。我们比较我们的新计算的结果，大型强子对撞机的数据和下一个领先的顺序预测，并找到一个数值上的显着影响的对数修正的形状的关键分布，这仍然是归一化后的横截面。
We present all-order predictions for Higgs boson production plus at least one jet which are accurate to leading logarithm in. 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 () 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.
