We present predictions for the gluon-fusion Higgs p_{T} spectrum at third resummed and fixed order (N^{3}LL^{'}+N^{3}LO) including fiducial cuts as required by experimental measurements at the Large Hadron Collider. Integrating the spectrum, we predict for the first time the total fiducial cross section to third order (N^{3}LO) and improved by resummation. The N^{3}LO correction is enhanced by cut-induced logarithmic effects and is not reproduced by the inclusive N^{3}LO correction times a lower-order acceptance. These are the highest-order predictions of their kind achieved so far at a hadron collider.
我们给出了在大型强子对撞机实验测量所需的基准切割条件下，胶子融合希格斯粒子横向动量谱在第三阶重整化和固定阶（N³LL′+N³LO）的预测。对该谱进行积分，我们首次预测了第三阶（N³LO）的总基准截面，并通过重整化得到了改进。N³LO修正因切割诱导的对数效应而增强，不能通过包含性N³LO修正乘以较低阶接受度来重现。这些是迄今为止在强子对撞机上获得的此类最高阶预测。
