论文摘要
我们报告了一条外壳腿的五粒子过程的两环散射振幅的计算进步。为了关注Higgs玻色子与底部夸克对的生产，我们概述了新开发的技术如何使我们能够克服计算瓶颈。特别是，我们讨论了有限场算术的使用，并阐明了一种方便的方式来评估振幅中出现的特殊功能。
We report on the advances in the calculation of the two-loop scattering amplitudes for five-particle processes with one off-shell leg. Focusing on the production of a Higgs boson in association with a bottom quark pair, we outline how the newly developed technology allows us to overcome the computational bottlenecks. In particular, we discuss the use of finite field arithmetic and elucidate a convenient way to evaluate numerically the special functions appearing in the amplitudes.
