强子对撞机上单顶夸克和第四代夸克t通道产生的NLO预言

NLO predictions for t-channel production of single top and fourth generation quarks at hadron colliders

John M. Campbell, Rikkert Frederix, Fabio Maltoni, Francesco Tramontano

摘要:

我们提出了更新的非线性光学预测在Tevatron和在LHC的重夸克的电弱t-通道生产。我们考虑从2到2和2到3玻恩过程出发的单顶和第四代t'的产生。首次给出了非线性光学条件下的tb'和t' b '截面的计算结果。深入研究了来自部分子分布函数、重整化和因式分解标度依赖性以及重夸克质量的理论不确定性。

英文摘要:

We present updated NLO predictions for the electroweak t-channel production of heavy quarks at the Tevatron and at the LHC. We consider production of single top and fourth generation t' starting from both 2 to 2 and 2 to 3 Born processes. Predictions for tb' and t'b' cross sections at NLO are also given for the first time. A thorough study of the theoretical uncertainties coming from parton distribution functions, renormalisation and factorisation scale dependence and heavy quark masses is performed.
