摘要：

Due to the exceptional performance of current and future colliders, the calculations for many scattering processes have been pushed to next-to-next-to-leading order(NNLO) and/or even higher order within the perturbative theory to match the experimental accuracy. However, the development of a framework capable of computing scattering amplitudes at any loop level has not materialized thus far. Recently, Prof. Yan-Qing Ma released the package CalcLoop which allows for the calculation of Feynman amplitudes with any number of loops, building upon his extensive work over the past decade. In this talk, I will provide an introduction to the fundamental usage of CalcLoop through illustrative examples. To access the package, you can download it from the following link: https://gitlab.com/multiloop-pku/calcloop.
