ILC上ee对撞产生tt夸克对

本文结合国际直线对撞机(ILC)的实验 讨论了 湮灭产生 对过程．在具体计算过程中，本文采用一种新的计算方式，即“混合链图传播子”修正下的反应截面，首先对QED中Dyson链图传播子理论在电弱统一标准模型中做了推广，获得WS中的光子、中间玻色子混合链图传播子，进而计算了 混合链图修正下 反应总截面 ，并与单圈修正下的总截面 和最低阶总截面 做了对比分析，发现在国际直线对撞机对撞能区， 对 和 的修正很大．此外，作者还结合国际直线对撞机的对撞亮度，讨论了每年可在ILC上产生 对的事例数．

The Production of tt Quark Pair Through ee Collider at ILC

In this paper we discussed the production of quark pair through the work of collider by means of the International Linear Collider (ILC) . A new method the mixed chain propagator correction was used to calculate the cross section of . Firstly we promoted the Dyson chain propagator theory of QED to the electroweak unification standard model and acquired the mixing chain propagators of photon and intermediate gauge boson in standard model. Then we calculated the total cross section of by the mixed chain propagator correction and compared it with the total cross sections by one loop correction and tree level. The numerical results showed that the corrections of to and are large. In addition, combined with the linear collider brightness we also discussed the number of pairs that can be produced each year at ILC.
