论文摘要
将NNLO QCD预测的触及到$ 2 \ to 3 $生产过程是LHC精确现象学计划的支柱之一。在本次演讲中，我们将概述最新的结果以及计算两循环五分幅度的发展，这有助于实现这一目标。我们将讨论在无质量五分散射之外的最先进的挑战方面遇到的挑战。然后，我们将提出一组足以表达任何具有外部巨型腿的平面两环五粒子散射幅度的基础。此基础大大促进了散射幅度的紧凑分析形式的推导，并打开了它们快速可靠的数值评估的可能性。在不久的将来，可以合理地预料到电子玻色子生产现象学的应用。
Pushing the reach of NNLO QCD predictions to $2\to3$ production processes is one of the pillars of precision phenomenology program at the LHC. In this talk we will overview recent results and developments in the calculation of two-loop five-point amplitudes contributing towards achieving this goal. We will discuss challenges encountered in advancing the state-of-the-art beyond the class of massless five-point scattering. We will then present a basis set of transcendental functions sufficient to express any planar two-loop five-particle scattering amplitude with one external massive leg. This basis greatly facilitates derivation of compact analytic form of scattering amplitudes, and opens a possibility of their fast and reliable numerical evaluation. Applications for phenomenology of electroweak boson production can be reasonably anticipated in the near future.
