藉由對撞機中所產生的正反頂夸克對，我們用以研究由電偶極矩及磁偶極矩所引起頂夸克與膠子之間的異常耦合。並藉由等效場論的方法,我們得以計算頂夸克的電偶極矩及磁偶極矩如何影響在對撞機中正反頂夸克對產生的散射截面。並將其理論計算的結果與兆電子伏特加速器(Tevatron)以及大型強子對撞機(LHC)最新的實驗結果進行對比，以了解偶極矩數值的許可範圍。接下來，我們利用兩種與頂夸克自旋數有關的不對稱值來觀察頂夸克的衰變產物。藉由此一方法我們可以觀察異常耦合的影響並給出偶極矩數值的限制。

Through top quark-pair production at hadron collider, we study the possible effects of nonstandard top-gluon couplings are composed of chromomagnetic dipole moments and chrmoelectric dipole moments, CMDM and CEDM, of top quarks. And using the effective operators, which produces anomalous coupling of top quark to calculate the total cross section for the top-pair production process pp/p¯p → t¯tX. By comparing the latest result of the total cross section at Tevatron and LHC, can us describe these anomalous coupling parameters as an allowed region on the coordinate plane. And
we found that there is a common space consist in all the region, which made by different experiment. Next we offer another method to give constraint on nonstandard top-gluon couplings by analysing the different type of asymmetries, and these asymmetries are related to the t¯t spin correlation. Then we compared to the LHC measurement result at 7 TeV to find out the possible values of anomalous top-gluon coupling parameters.
