We provide a quantitative determination of the effective partonic kinematics for Higgs boson production in gluon fusion in terms of the collider energy at the LHC. We use the result to assess, as a function of the Higgs boson mass, whether the large m(t) approximation is adequate and Sudakov resummation advantageous. We argue that our results hold to all perturbative orders. Based on our results, we conclude that the full inclusion of finite top mass corrections is likely to be important for accurate phenomenology for a light Higgs boson with m(H)~125 GeV at the LHC with √s=14 TeV.
我们提供了一种定量方法，用于确定 LHC 中胶子融合产生 Higgs 玻色子过程中的有效部分子动力学，该方法基于对撞机能量。我们使用该结果来评估在 Higgs 玻色子质量的函数中，大 mt 近似是否充分以及 Sudakov 再求和是否有利。我们认为我们的结果在所有的微扰阶都是成立的。基于我们的结果，我们得出结论，对于在 LHC 中具有 m(H)~125 GeV 的轻 Higgs 玻色子，在 √s=14 TeV 时，准确的唯象学研究很可能需要包含有限的 top 质量修正。
