Mauro Chiesa, Ansgar Denner, Jean-Nicolas Lang

摘要:

在LHC中产生Diboson是一个非常重要的过程,无论是在SM的测试背景下,还是直接寻找新的物理。在本文中,我们提出了一个唯象研究的WW,WZ,和ZZ生产考虑事件的选择感兴趣的异常三规范玻色子耦合搜索在LHC:我们提供的理论预测在标准模型在NLO QCD和NLO EW的准确性和研究的影响,异常三规范玻色子相互作用在NLO QCD。对于WW和ZZ的产生,胶子引发的环诱导过程的贡献。反常的三规范玻色子相互作用参数化的EFT框架。本文是RECOLA2在EFT中的首次应用。

英文摘要:

Diboson production at the LHC is a process of great importance both in the context of tests of the SM and for direct searches for new physics. In this paper we present a phenomenological study of WW, WZ, and ZZ production considering event selections of interest for the anomalous triple-gauge-boson-coupling searches at the LHC: we provide theoretical predictions within the Standard Model at NLO QCD and NLO EW accuracy and study the effect of the anomalous triple-gauge-boson interactions at NLO QCD. For WW and ZZ production, the contribution of the gluon-initiated loop-induced processes is included. Anomalous triple-gauge-boson interactions are parametrized in the EFT framework. This paper is the first application of RECOLA2 in the EFT context.
