论文摘要
我们计算第三代夸克（$ t，\ b $）对Gluon Fusion $ gg \ to ww $的两回路振幅的贡献。我们介绍了跨党相空间振幅的图以及两个运动点的参考值。通过数值求解普通微分方程的系统，可以有效地评估主积分。
We compute the contribution of third generation quarks ($t,\ b$) to the two-loop amplitude for on-shell $W$ boson pair production in gluon fusion $gg \to WW$. We present plots for the amplitude across partonic phase space as well as reference values for two kinematic points. The master integrals are efficiently evaluated by numerically solving a system of ordinary differential equations.
