本文简单介绍粒子物理模拟软件包FeynRules和MadGraph5,运用FeynRules软件包产生出第四代夸克的模型文件,并运用粒子物理MadGraph软件主要模拟在大型强子对撞机中产生第四代夸克b’或t’对事例及其算出散射截面。
In this paper, we simply introduce the particle physics simulation software package FeynRules and Madgraph5, use FeynRules software package to produce the fourth generation quark model file, and use Madgraph software to simulate the fourth generation of quarks b' or t' in the Large Hadron Collider, and finally we calculate the scattering cross section.
