我们阐明了一种通过胶子-胶子融合来估计希格斯粒子产生多个(至少两个)硬喷流的新技术。该方法基于高能因式分解，通过对已知所有阶结果所产生的散射幅度的分析行为的约束来扩展适用范围。该方法近似真实和虚拟修正，并允许在包含n-Parton的事件样本中恢复在高能极限中占主导地位的项。所得到的近似与用于产生希格斯玻色子的已知树级矩阵元素相匹配，并在蒙特卡罗生成器中实现。文中给出了算例结果，并讨论了特征辐射方向图。
We elucidate a new technique for estimating the production of multiple (at least two) hard jets in Higgs production via gluon-gluon fusion. The approach is based upon high energy factorisation, with the region of applicability extended by constraints on the analytic behaviour of the scattering amplitudes stemming from known all-order results. The method approximates both real and virtual corrections, and allows for the resummation in an n-parton inclusive event sample of the terms dominant in the high energy limit. The resulting approximation is matched to the known tree level matrix elements for the production of a Higgs boson in association with 2 and 3 jets, and implemented in a Monte Carlo generator. Example results are presented and characteristic radiation patterns discussed.
