论文摘要

我们与Gluon Fusion的$ Z $ Boson联合介绍了Higgs生产的完全差异化订单结果。我们的两循环虚拟贡献使用扇区分解(包括完整的顶级质量效应)进行数值评估,并通过分析高能量扩展为订单以高$ p_t $补充($ M_z^4,M_H^4,M_H^4,M_T^4,M_T^{32} $)。使用扩展的结果,我们还提出了一项对大型$ P_T $的顶级质量计划不确定性的研究。

We present fully differential next-to-leading order results for Higgs production in association with a $Z$ boson in gluon fusion. Our two-loop virtual contributions are evaluated numerically using sector decomposition, including full top-quark mass effects, and supplemented at high $p_T$ by an analytic high-energy expansion to order ($m_Z^4, m_H^4, m_t^{32}$). Using the expanded results we also present a study of the top-quark mass scheme uncertainty at large $p_T$.
