论文摘要
我们在低和高能量限制中计算了$ gg \ to zz $的次订单虚拟订单虚拟的两循环校正，考虑到虚拟顶级夸克的贡献。提出了所有20个形式的分析结果，包括最高$ 1/m_t^{12} $和$ m_t^{32} $的扩展项。我们使用PADé近似程序来扩展高能扩展的收敛半径，并将这种方法应用于Fini \ te Virtual sext-exter-to-Leading Ording校正。
We compute next-to-leading order virtual two-loop corrections to the process $gg\to ZZ$ in the low- and high-energy limits, considering the contributions with virtual top quarks. Analytic results for all 20 form factors are presented including expansion terms up to $1/m_t^{12}$ and $m_t^{32}$. We use a Padé approximation procedure to extend the radius of convergence of the high-energy expansion and apply this approach to the fini\ te virtual next-to-leading order corrections.
