标题： Forward Higgs production within high energy factorization in the heavy quark limit at next-to-leading order accuracy

摘要： 我们使用Lipatov的高能有效作用量，在高能因子化框架下，利用无限顶夸克质量极限来确定在前向区域中希格斯粒子产生的次领头阶修正。 我们的结果基于对实修正的显式计算，以及Nefedov之前确定的虚修正。 作为新元素，我们在高能有效作用量框架内提供了所需次领头阶系数的正确定义，扩展了之前提出的方案。 我们进一步提出了一种减法机制，以在存在外部非定域腿的情况下，实现该系数中实和虚红外奇点的稳定抵消。 除了对于直接现象学研究（如希格斯+喷注构型的高能重求和）的相关性外，我们的结果还将用于高能极限下横向动量依赖因子化的研究。 显示英文摘要

摘要： We use Lipatov's high energy effective action to determine the next-to-leading order corrections to Higgs production in the forward region within high energy factorization making use of the infinite top mass limit. Our result is based on an explicit calculation of real corrections combined with virtual corrections determined earlier by Nefedov. As a new element we provide a proper definition of the desired next-to-leading order coefficient within the high energy effective action framework, extending a previously proposed prescription. We further propose a subtraction mechanism to achieve for this coefficient a stable cancellation of real and virtual infra-red singularities in the presence of external off-shell legs. Apart from its relevance for direct phenomenological studies, such as high energy resummation of Higgs + jet configurations, our result will be further of use for the study of transverse momentum dependent factorization in the high energy limit.
