对与部分子簇射相匹配的双玻色子产生的NLO QCD + NLO EW修正

NLO QCD+NLO EW corrections to diboson production matched to parton shower

Mauro Chiesa, Carlo Oleari, Emanuele Re

摘要:

本文介绍了在LHC上用非线性光学QCD和非线性光学EW修正对部分子簇射产生矢量玻色子对的匹配。我们考虑轻子末态,包括共振和非共振图,自旋关联和离壳效应。我们的研究结果是通过将Recola 2-Collier单循环提供程序与POWHEG-BOX-RES框架相结合获得的。我们讨论我们的实现,我们验证它在固定的顺序,我们显示我们的最终结果匹配部分子淋浴。我们工作的一个副产品也是Recola 2-Collier和POWHEG-BOX-RES之间的一般接口。这是第一次EW和QCD修正diboson生产一致匹配的部分子淋浴。

英文摘要:

We present the matching of NLO QCD and NLO EW corrections to parton showers for vector-boson pair production at the LHC. We consider leptonic final states, including resonant and non-resonant diagrams, spin correlations and off-shell effects. Our results are obtained interfacing the Recola2-Collier one-loop provider with the POWHEG-BOX-RES framework. We discuss our implementation, we validate it at fixed order, and we show our final results matched to parton shower. A by-product of our work is also a general interface between Recola2-Collier and POWHEG-BOX-RES. This is the first time that EW and QCD corrections to diboson production are consistently matched to parton showers.
