Resummation of QCD corrections for hard processes at the LHC

大型强子对撞机是一台强子机器，它具有巨大的潜力，可以以前所未有的精度测试标准模型，并探索标准模型之外的物理学。在大型强子对撞机上进行精确的研究是高能物理最重要的目标之一。为了与实验结果进行详细的比较，微扰量子色动力学的高阶预测起着重要的作用。我们建议承担的任务，计算高阶辐射校正从量子色动力学的生产对矢量玻色子，如Zs和WS。特别是，我们将集中在微扰理论中的二阶微分分布。我们还将系统地包括阈值效应，特别是横向动量分布。这就需要建立一个形式体系，以及在微扰论中计算各种普遍的反常维数。我们的预测对理解大型强子对撞机的结果很重要。

The Large Hadron Collider, being a hadronic machine, has an immense potential to test the Standard Model to unprecedented accuracy and also to probe physics beyond the Standard Model. Precision studies at the Large Hadron Collider are one of the most important goals in high energy physics. In order to make the detailed comparison with the experimental results, higher order predictions from perturbative Quantum Chromodynamics play important role. We propose to undertake the task of computing higher order radiative corrections from Quantum Chromodynamics to the production of pair of vector bosons such as Zs and Ws. In particular, we will focus on the differential distributions at second order in perturbation theory. We will also systematically include threshold effects in particular for the transverse momentum distributions. This requires setting up a formalism as well as computation of various universal anomalous dimensions in perturbation theory. Our predictions will be important to understand the results at the Large Hadron Collider.
