在LHC上矢量玻色子的产生:QCD和电弱效应

Vector-boson production at the LHC: QCD and electroweak effects

Tobias Kasprzik

摘要:

对矢量玻色子产生过程的深刻理解对LHC至关重要。相应的截面很大,轻子衰变模中清晰的信号使最终态很容易重构。因此,这些过程在各种新物理信号中扮演着重要的背景角色,它们可能有助于更好地理解强子对撞机环境中的标准模型物理。本文综述了LHC中矢量玻色子产生中高阶QCD和电弱效应的理论描述的最新进展,讨论了Drell-Yan过程、矢量玻色子对产生和伴随喷流的矢量玻色子产生。

英文摘要:

A profound understanding of vector-boson production processes is of crucial importance at the LHC. The corresponding cross sections are large, and the final states are easy to reconstruct due to the clean signatures in the leptonic decay modes. Therefore, such processes play an important role as backgrounds in a large variety of new-physics signals, and they may furthermore help to better understand the well-established Standard-Model physics in a hadron-collider environment. We review the recent progress in the theoretical description of higher-order QCD and electroweak effects in vector-boson production at the LHC, discussing the Drell--Yan process, vector-boson pair production and vector-boson production with associated jets.
