使用有效场论的方法，我们推导出第一个全阶因式分解定理的希格斯玻色子生产截面与喷气否决权，施加通过一个标准的顺序重组喷气算法。就像在Drell-Yan和Higgs产生中的小q T重化的情况下，因子分解受到共线异常的影响。我们的分析提供了一个系统的recremation的基础上，大programmesbeyond领先的对数阶。具体来说，我们提出的预测，在下一个到下一个到领先的对数阶的cummed jetveto横截面和效率。我们的研究结果具有重要意义的希格斯玻色子搜索在大型强子对撞机，在那里需要一个喷气否决权，以抑制背景事件。
Using methods of effective field theory, we derive the first all-order factorization theorem for the Higgs-boson production cross section with a jet veto, imposed by means of a standard sequential recombination jet algorithm. Like in the case of small-q T resummation in Drell-Yan and Higgs production, the factorization is affected by a collinear anomaly. Our analysis provides the basis for a systematic resummation of large logarithmsbeyond leading-logarithmic order. Specifically, we present predictions for the resummed jetveto cross section and efficiency at next-to-next-to-leading logarithmic order. Our results have important implications for Higgs-boson searches at the LHC, where a jet veto is required to suppress background events.
