摘要:

IBP reduction is taking center stage in high order perturbative calculations of scattering amplitudes. Recently, we released the reduction package Blade which is based on the method of block-triangular form. Compared to reduction packages on the market, Blade can usually improve the efficiency of IBP reduction by 1-2 orders. In this talk, I will introduce the usage of Blade and discuss its properties by several examples. The package can be downloaded from https://gitlab.com/multiloop-pku/blade
