论文摘要
我们使用Lipatov的高能量有效动作来确定在高能量分解内的近距离校正，以利用无限的最高质量限制。我们的结果是基于对真实校正的明确计算与Nefedov先前确定的虚拟校正相结合的。作为一个新元素，我们提供了适当的定义，以在高能量有效的动作框架内进行所需的临近订单系数，从而扩展了先前提出的处方。我们进一步提出了一种减法机制，以实现这种系数，在存在外部外壳腿的情况下，可以稳定地取消真实和虚拟红外的奇异性。除了它与直接现象学研究的相关性（例如Higgs + Jet构型的高能量重新召集）外，我们的结果还将进一步用于研究高能量限制中横向动量依赖性分解。
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.
