论文摘要
我们回顾了对在四个维量子场理论中自旋的颗粒散射幅度的单位性和交叉约束。作为应用程序,我们详细研究了中性自旋1/2费米的两到两个散射。假设其散射幅度的mandelstam分析性,我们使用数值S-Matrix Bootstrap方法来估计四分之一和立方(Yukawa)耦合的各种非扰动界限。
We review unitarity and crossing constraints on scattering amplitudes for particles with spin in four dimensional quantum field theories. As an application we study two to two scattering of neutral spin 1/2 fermions in detail. Assuming Mandelstam analyticity of its scattering amplitude, we use the numerical S-matrix bootstrap method to estimate various non-perturbative bounds on quartic and cubic (Yukawa) couplings.
