摘要
顶夸克是标准模型中最重的粒子,它的发现进一步验证了标准模型的正确性,并为人们探索标准模型之外的新物理提供了新的手段.在实验上,高能碰撞是研究顶夸克的唯一途径.在多源热模型框架下对Tsallis分布与逆幂律分布函数进行改进,运用改进后的双组分统计分布对产生顶夸克的碰撞反应系统中末态粒子的横动量分布进行描述,提取出相关的参数值.
Abstract
In the Standard Model,the top quark is the heaviestparticle.The top quark verifies the correctness of the standard Model and provides a new way for people to explore new physics be-yond the standard model.Highenergy collision is the only way to study top quarks experimentally.Tsal-lis distribution and inverse power law distribution function could be superimposed under the framework of multi-source heat model.The transverse momentum distributions of the top quarks are described by using the two-component statistical distributionand the related parameters are extracted.
