摘要：

本文研究了在标准模型的非对易扩展条件下大型强子对撞机上的Drell-Yan过程。利用Seiberg-Witten映射，我们计算了非对易参数$Θ_{μν}$中的一阶产生截面.虽然这一思想的发展由来已久，但迄今为止所做的唯象分析仍然有限，而且主要是在直线对撞机的背景下进行的。这个非极小非交换标准模型的一些突出特点不仅改变了SM产生通道上的耦合，而且允许额外的非标准顶点发挥重要作用。因此，在Drell-Yan过程中，如在本分析中所研究的，还需要在树水平上考虑胶子融合过程。一些特征信号，如振荡的方位角分布是动量相关的有效耦合的结果。我们探讨了非交换尺度$Λ_{NC} \ge 0.4~\rm{TeV}$考虑不同的机器能量范围从$7~\rm{TeV}$到$13~\rm{TeV}$。

英文摘要：

We study the Drell-Yan process at the Large Hadron Collider in presence of the noncommutative extension of standard model. Using the Seiberg-Witten map, we calculate the production cross-section to the first order in the noncommutative parameter $Θ_{μν}$. Although this idea is evolving for long, limited amount of phenomenological analysis was done so far and dominantly in the context of linear collider. Some outstanding feature from this non-minimal noncommutative standard model not only modify the couplings over SM production channel, also allow additional nonstandard vertices which can play a significant role. Hence in the Drell-Yan process, as studied in present analysis, one also needs to account for gluon fusion process at the tree level. Some of the characteristic signatures such as oscillatory azimuthal distributions are outcome of the momentum dependent effective couplings. We explore the noncommutative scale $Λ_{NC} \ge 0.4~\rm{TeV}$ considering different machine energy ranging from $7~\rm{TeV}$ to $13~\rm{TeV}$.
