论文摘要
我们强调了用大量内部传播器计算高阶散射幅度的最新发展。贡献的Feynman积分通常会导致特殊类别的功能，例如与椭圆曲线相关的功能。随着幅度中有更多量表的存在，必须更好地了解贡献的Feynman积分，并使用当前的尖端技术来解决分析和代数复杂性的增长。特别是，我们首先讨论用于顶级对生产的两环散射幅度，并以激发五点过程的近代到隔壁的前阶校正的重要步骤结论。
We highlight the latest developments in computing higher-order scattering amplitudes with massive internal propagators. The contributing Feynman integrals often lead to special classes of functions, for example, functions associated with elliptic curves. With the presence of more scales in the amplitudes, it becomes imperative to have a better understanding of the contributing Feynman integrals and using current cutting-edge technologies to tackle the growth in analytic and algebraic complexities. In particular, we start with discussing two-loop scattering amplitudes for top-quark pair production and conclude with motivating important steps towards obtaining next-to-next-to leading-order corrections for five-point processes.
