We compute the cross section for the production of a high-mass photon pair in association with two hadronic jets to next-to-leading order in quantum chromodynamics. Our results allow us for the first time to reliably predict the absolute normalization of this process and demonstrate that the shape of important kinematical distributions is modified by higher-order effects. The perturbative corrections will be an important ingredient in precision studies of Higgs boson properties from its production in association with two jets.
我们计算了在量子色动力学的次领头阶下，伴随两个强子喷注产生一对高质量光子的截面。我们的结果首次允许可靠地预测这个过程的绝对归一化，并表明高阶效应会改变重要的运动学分布的形状。在研究通过两个喷注产生的希格斯玻色子性质的精密研究中，微扰修正将是一个重要的组成部分。
