论文摘要
我们在高能量和大型$ m_t $限制中计算了该过程$ gg \ to zh $的党派横截面的临近订单虚拟校正。我们使用padé近似值来增加$ m_t^2/s $,$ m_t^2/t $和$ m_t^2/u $的高能量扩展的收敛半径,并证明可以将精确的结果获得到相当接近Top Quark Pair Pair Pair Threshold的能量。我们介绍了形式因素和临近领先顺序虚拟横截面的结果。
We compute the next-to-leading order virtual corrections to the partonic cross-section of the process $gg\to ZH$, in the high-energy and large-$m_t$ limits. We use Padé approximants to increase the radius of convergence of the high-energy expansion in $m_t^2/s$, $m_t^2/t$ and $m_t^2/u$ and show that precise results can be obtained down to energies which are fairly close to the top quark pair threshold. We present results both for the form factors and the next-to-leading order virtual cross-section.
