在LHeC和FCC-eh上寻找顶夸克对产生截面

Searching for top quark pair production cross section at LHeC and FCC-eh

B. Rezaei, G. R. Boroun

摘要:

考虑了在LHeC和FCC-eh中产生的$t\overline{t}$对的深度非弹性散射模式。提出了一种提取与横向结构函数$F_{2}(x,Q^{2})$参数化相关的顶部约化截面的方法。数值计算与已知的运动学的LHeC和FCC-eh对撞机的演示。魅力和美丽对生产所获得的结果与实验数据是可比的。我们发现,对于一个广泛的动量转移到顶夸克对,约化截面是很好地描述了质心能量。

英文摘要:

The deep inelastic scattering mode of $t\overline{t}$ pair production at the proposed LHeC and FCC-eh is considered. We present a method to extract the top reduced cross section related to the transversal structure function $F_{2}(x,Q^{2})$ parameterization. Numerical calculations with known kinematics of the LHeC and FCC-eh colliders are demonstrated. The results obtained for charm and beauty pair production are comparable with the experimental data. We show that for a wide range of the momentum transfer into the top quark pair, the reduced cross section is well described by center-of-mass energies.
