Zero and one jet combined NLO analysis of the top quark forward-backward asymmetry

Stefan Hoeche, Junwu Huang, Gionata Luisoni, Marek Schoenherr, Jan Winter

摘要:

本文分析了在Tevatron对撞机上产生顶夸克对的前后不对称性。我们使用新的Monte Carlo方法合并矩阵元素和部分子阵雨结合非线性QCD预测TT和TT+喷生产。详细量化了理论上的不确定性。我们发现协议与实验数据的横向动量依赖的不对称性。

英文摘要:

We present an analysis of the forward-backward asymmetry in the production of top quark pairs at the Tevatron collider. We use novel Monte Carlo methods for merging matrix elements and parton showers to combine NLO QCD predictions for tt and tt+jet production. Theoretical uncertainties are quantified in detail. We find agreement with experimental data on the transverse momentum dependence of the asymmetry.
