在LHC上对矢量玻色子融合中W+ W+ jj产生的NLO QCD修正

NLO QCD corrections to W+ W+ jj production in vector-boson fusion at the LHC

Ansgar Denner, Lucia Hosekova, Stefan Kallweit

摘要:

本文提出了一个次首阶QCD方法,计算了矢量玻色子融合中e+νeμ+νμjj的产生,即两个带正电荷的W玻色子在LHC上的散射.我们包括一套完整的电弱领先的顺序图的六粒子的最终状态和定量评估的大小的s-通道和干扰的贡献VBF运动学。计算使用复杂的质量计划来描述的W-玻色子共振,并实施到一个灵活的蒙特卡罗发生器。使用基于喷流横动量的动力学尺度,对于所有考虑的观测量,QCD修正保持在10%以下,而剩余尺度依赖性在1%的水平。

英文摘要:

We present a next-to-leading-order QCD calculation for e+νeμ+νμjj production in vector-boson fusion, i.e. the scattering of two positively charged W bosons at the LHC. We include the complete set of electroweak leading-order diagrams for the six-particle final state and quantitatively assess the size of the s-channel and interference contributions in VBF kinematics. The calculation uses the complex-mass scheme to describe the W-boson resonances and is implemented into a flexible Monte Carlo generator. Using a dynamical scale based on the transverse momenta of the jets, the QCD corrections stay below about 10% for all considered observables, while the residual scale dependence is at the level of 1%.
