摘要

在这篇贡献中，我将提出新的想法来简化形式因子方法，以便直接在所谓的' t Hooft-Veltman格式中计算多回路多腿散射振幅的螺旋振幅，避免格式定义中的消失结构和模糊性。

Tensor decomposition for multiloop, multileg helicity amplitudes

In this contribution I will present new ideas to simplify the form factor method in order to compute helicity amplitudes for multiloop multileg scattering amplitudes, directly in the so-called ’t Hooft-Veltman scheme, avoiding evanescent structures and ambiguities in the scheme deﬁnitions.
