论文摘要
我们介绍了Caravel的第一个公共版本，Caravel是基于数值单位方法的量子场理论中多环散射幅度计算的C ++ 17框架。 Caravel由用于$ d $二维的模块组成，将散射振幅的集成量分解为主术语和表面术语，在浮点或有限场算术中的树级振幅的计算，对QCD和EinSinein Grvertity和EinStientions QCD中的一个和两弹性放大器的数值计算，以及功能恢复性。我们提供展示Caravel的主要功能的程序，并允许计算选定的一环幅度和两层振幅。
We present the first public version of Caravel, a C++17 framework for the computation of multi-loop scattering amplitudes in quantum field theory, based on the numerical unitarity method. Caravel is composed of modules for the $D$-dimensional decomposition of integrands of scattering amplitudes into master and surface terms, the computation of tree-level amplitudes in floating point or finite-field arithmetic, the numerical computation of one- and two-loop amplitudes in QCD and Einstein gravity, and functional reconstruction tools. We provide programs that showcase Caravel's main functionalities and allow to compute selected one- and two-loop amplitudes.
