ILC上e+e-对撞产生t+t-夸克对
The production of t+ t-quark pair through e+ e-collider at ILC
摘要
Abstract
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 e+ e-→ t+ t-.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 e+ e-→ t+ t-by the mixed chain propagator correction and compared it with the total cross sections by one loop correction σloop and tree level σ0.The numerical results showed that the corrections of σchain to σloop and σ0 are large.In addition,combined with the linear collider brightness we also discussed the number of t+ t-pairs that can be produced each year at ILC.关键词
