论文摘要
在本文中，我们详细介绍了将多旋转多重散射幅度分解为Lorentz-Invariant形式因素的方法，从而利用了考虑四维外部状态而产生的简化。我们提出了一种简单而通用的方法，该方法既适用于费米子和骨气振幅，又使我们能够确定最少数量的物理相关形式，这可以与独立的螺旋性幅度一对一相关。我们明确讨论其对与LHC物理学相关的各种四点散射幅度的适用性。
In this paper, we elaborate on a method to decompose multiloop multileg scattering amplitudes into Lorentz-invariant form factors, which exploits the simplifications that arise from considering four-dimensional external states. We propose a simple and general approach that applies to both fermionic and bosonic amplitudes and allows us to identify a minimal number of physically relevant form factors, which can be related one-to-one to the independent helicity amplitudes. We discuss explicitly its applicability to various four- and five-point scattering amplitudes relevant for LHC physics.
