The first study of the angular distribution of μ^{+}μ^{-} pairs produced in the forward rapidity region via the Drell-Yan reaction pp→γ^{*}/Z+X→ℓ^{+}ℓ^{-}+X is presented, using data collected with the LHCb detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.1 fb^{-1}. The coefficients of the five leading terms in the angular distribution are determined as a function of the dimuon transverse momentum and rapidity. The results are compared to various theoretical predictions of the Z-boson production mechanism and can also be used to probe transverse-momentum-dependent parton distributions within the proton.
本文展示了通过Drell-Yan反应pp→γ*/Z+X→ℓ⁺ℓ⁻+X在向前快度区域产生的μ⁺μ⁻对的角分布的首次研究，使用了在大型强子对撞机底夸克探测器（LHCb）上收集的质心能量为13 TeV的数据，对应积分亮度为5.1 fb⁻¹。角分布中五个主要项的系数被确定为双μ子横向动量和快度的函数。结果与Z玻色子产生机制的各种理论预测进行了比较，并且还可用于探测质子内与横向动量相关的部分子分布。
