扭转时空对强子对撞机上$t\bar{t}$观测量的影响

Impact of Torsion Space-Time on $t\bar{t}$ observables at Hadron Colliders

Seyed Yaser Ayazi, Mojtaba Mohammadi Najafabadi

摘要:

本文从有效挠率时空模型出发,研究了它对强子对撞机顶对产生截面的影响。我们还研究了该模型对Tevatron和LHC的顶对不对称性的影响。我们发现,扭转时空可以解释的前向后不对称性,根据测量异常在Tevatron。我们在参数空间中找到了一个允许的区域,它可以同时满足在Tevatron和LHC上测量的所有$t\bar{t}$观测值。

英文摘要:

Starting from the effective torsion space-time model, we study its effects on the top pair production cross section at hadron colliders. We also study the effect of this model on top pair asymmetries at the Tevatron and the LHC. We find that torsion space-time can explain forward-backward asymmetry according to measured anomaly at Tevatron. We find an allowed region in the parameters space which can satisfy simultaneously all $t\bar{t}$ observables measured at Tevatron and LHC.
