在LHC上电弱规范玻色子的极化

Polarisation of electroweak gauge bosons at the LHC

James Stirling, Eleni Vryonidou

摘要:

我们目前的结果在大型强子对撞机产生的规范玻色子的极化。W玻色子的极化效应表现在轻子的角分布、轻子的横动量分布和缺失横能分布上。讨论了一系列不同的过程中产生W玻色子,如W+射流和W从顶部生产的偏振。不同偏振态的相对贡献随过程而变化,反映了底层硬散射过程的动态。我们还计算了在大型强子对撞机上与QCD喷流有关的Z玻色子的偏振。

英文摘要:

We present results for the polarisation of gauge bosons produced at the LHC. Polarisation effects for W bosons manifest themselves in the angular distributions of the lepton and in the distributions of lepton transverse momentum and missing transverse energy. The polarisation is discussed for a range of different processes producing W bosons such as W+jets and W from top production. The relative contributions of the different polarisation states vary from process to process, reflecting the dynamics of the underlying hard-scattering process. We also calculate the polarisation of the Z boson produced in association with QCD jets at the LHC.
